Device tab stays hardware-only (pins, wiring, may vary per workstation);
the Channels window owns the profile-facing identity. Concretely:
- Fix a real regression: SerialDevice generic-format Apply & Reconnect
nulled out custom channel_names/units every time (no fallback, unlike
every other optional field in reconfigure()), silently reverting to
sig0/sig1/... ids.
- Plot legend now live-tracks the current Signal/Channel name instead of
freezing tr.label at add-time, so a rename shows up without re-adding
the trace.
- Add an inline quick-reconnect (combo + button, pre-selects the actual
current source) directly on each Channel block in the Channels window,
for the common single-source case — rewiring hardware no longer means
touching every Plot/pipeline that referenced it.
- Collapse the Channel ID field behind an "ID ▸" advanced toggle;
channel_id is already auto-derived from the name (_slug_id) and rarely
needs to be seen.
- Devices tab's Signal "Name" column relabeled "Label" with a tooltip —
de-emphasized now that Channel name is the real identity.
- Move "create a Channel from this Signal" from a column on the Devices
tab's signal table to a ⊕ button on each Signal row in the Channels
tab's Namespace panel — the action now lives where the identity is
created, not on the hardware tab. Only that instance opts in
(on_create_channel); the read-only Namespace dock on the main window
is unaffected.
- Floor the Namespace panel's width at its columns' natural size so
dragging the Channels-tab splitter narrower can't push the ⊕ column
behind the horizontal scrollbar.
- Breadcrumb log when a profile-saved Signal override can't be applied
because the signal_id no longer exists.

Arduino analog Signal ids used to be the pin name itself, so fixing a
wrong pin silently changed the id and orphaned any plot trace, control,
or filter pipeline pointing at it. Analog Signal ids are now positional
(ai0, ai1, ...) and decoupled from the underlying pin, matching how
digital I/O already worked.
More broadly, formalizes a Device -> Signal -> Channel -> Plot naming
model (SignalConfig for physical device channels, Channel for derived/
computed ones) and adds core/reference_registry.py to propagate any
Signal or Channel id rename through plot traces, controls, and filter
pipelines instead of leaving them dangling. Signal ids are now editable
in the Signals tab with the same propagation.
.labui profile schema bumped to v2.0 with a transparent migration for
old files, including remapping old pin-name Signal ids to the new
positional ones. Removed six confirmed-dead files (two legacy device
classes, four superseded top-level ui/ duplicates).

Several compounding freeze sources in plugins/motion_capture/:
- tracker.py: _run_real had no frame-rate cap independent of the camera's
configured fps (up to 120fps/2560x1440 was possible), and no bound on
consecutive failed reads — a camera that "opens" (cv2 isOpened() can lie,
seen with Windows MSMF/obsensor) but never actually delivers frames would
get hammered forever. Added a 20Hz processing cap, a real test-read before
committing to a camera, and a give-up-after-30-failures fallback to
simulation.
- tracker.py/device.py: cv2.VideoCapture() opening a real camera is a slow,
blocking call — CameraTracker.start() used to do this synchronously on
the caller's thread, which froze the whole app when ProfileManager.apply()
called it during profile load. Now runs on the background thread; status
reporting (CameraDevice) moved to an on_result callback since the caller
can no longer learn the outcome synchronously.
- window.py: the Camera View preview ran a 30Hz GUI-thread timer doing a
full-frame copy + QImage/QPixmap rebuild every tick unconditionally (no
visibility check) — dropped to 10Hz and skips entirely when hidden.
Camera enumeration (list_cameras(), up to 8 sequential cv2.VideoCapture
probes) also ran inline in the window constructor, blocking it open the
same way camera_panel.py's CameraScanThread already avoided for the Add
Device dialog — moved to the same async pattern here.
config_window.py: separately, ConfigWindow._dev_poll (device status label
refresh) was stopped in closeEvent and never restarted, since MainWindow
reuses the same ConfigWindow instance across opens — invisible before
because connect() was synchronous, but with the above change a device can
sit in CONNECTING for a while, and a stale poll made that look stuck
forever after reopening the window. Restart it in showEvent.

Channel ID renames
Generalized the Plot pane drag-to-reorder (_PaneDragHandle/_PlotDropContainer
-> _DragHandle/_DragReorderContainer) and reused it for the Channels tab's
derived-channel list; reordering also updates SignalProcessor's evaluation
order (list order matters for chained Channels) via new reorder_derived().
Namespace panel: added an ID column (bare channel_id, matching the actual
channels.get(...) script convention) and fixed the Source column for
Channels to show resolved absolute references (dev_id/ch_id for a Signal,
bare id for a chained Channel) instead of the operation kind, so a chain
is traceable by eye.
Fixed a real bug this surfaced: renaming a Channel's ID never propagated
to other Channels' sources, leaving dangling ("derived", old_id)
references that silently stopped updating. Added
SignalProcessor.rename_derived() to fix up sources plus carry the ring
buffer/latest-value cache to the new key, wired to DerivedBlock's Apply.

Devices tab split into Physical Devices (left) / Signals (right); Channels
tab now hosts the Namespace browser (left) alongside Channels (right,
larger by default). Plot Builder panes gain drag-to-reorder (same mechanics
as ControlPanel's widget list, adapted for the editable pane title via a
dedicated grip icon), "+ Add Channel" moved beside Size for a more compact
row, and Min/Max/Size/line-width spin boxes widened so values no longer
overlap the up/down arrows.

- Split device tab into pysical devices and signals.
- Replaced old Signals panel (under Channels tab) with namespace.
to make Channel creation easier.

Devices: auto-name from OS-reported port description (Device Manager /
udev string) instead of a generic label; default Serial #Channels 1;
consistent simulate-mode checkbox across backends; inline device rename.
Channels: calibration/filters move out of Signals into a Channel
"Operation" (adds Scale/Offset alongside the existing math kinds);
single-physical-source Channels get an embedded Filters block; new
Channels auto-name/auto-ID from their source and reject duplicate
names/IDs on apply; "Create Channel" button on each Signal row; renamed
"Sources" -> "Signals" in the Channels UI; Signals' READ/WRITE dir badge
(was silently-broken IN/OUT) now reflects the real writable flag.
Plot: default layout is one pane per Channel (not per device, not raw
Signals) titled by channel name; "+ Add Channel" is a checkbox dialog
instead of an inline dropdown; traces get up/down reorder; live unit
changes (e.g. a Mark-10 gauge switching lb/kgF/N/ozF) propagate to an
open pane's axis label without clobbering a manually-typed one.
Control Panel: hardware assignment now picks from the same writable-
Signals list instead of a separate device/channel combo with a
hardcoded Arduino pin list; stale visual indicator when a control's
target device/channel disconnects or disappears; documented the `vars`
bridge (Control Panel On Action Script <-> Channel scripts) in both
directions' help text and script templates.

Replaces three separate floating windows with single tabbed ConfigWindow:
- Tab 0: Devices (device cards, add/remove/configure)
- Tab 1: Channels (signal table with Dir/IN/OUT badge + pipeline ⚙ per row; derived channels pane)
- Tab 2: Plot (layout canvas + pane config)
Adds is_output field to ChannelConfig for output channel direction badges.
