Persist dock layout to profiles; dedupe port names; Channels-tab Create button

2026-09-21T05:45:18Z

- Fix duplicated device names ("FT231X USB UART - FT231X USB UART (...)") — pyserial on Linux often reports the same udev model string twice for cheap FTDI/CH340-style adapters. Collapse it at the list_ports() source so every consumer (device auto-name, port picker) benefits. - Save Control Panel / Namespace dock area, floating geometry, visibility, size and order to .labui profiles via QMainWindow.saveState()/ restoreState(), round-tripped through the existing Profile.settings passthrough (self._settings) — no profile schema change needed. - Channels tab: replace the per-row Signal ⊕ button (and its pinned/ frozen-column overlay) with a single "Create Channel" button below the Namespace panel. Select one or more Signal/Channel rows (multi-select now supported) and click it — selected rows become the new Channel's sources, or an empty Channel is created if nothing's selected. Fixes a bug in the process: the multi/zero-source path defaulted to kind="expression" with no expression text, which fails to compile and silently dropped the channel; use kind="none" instead, which the user then edits in the Channels pane. NamespacePanel itself (ui/namespace_panel.py) goes back to a plain read-only reference widget — the create-channel button and its logic live entirely in ConfigWindow (config_window.py), so the shared dockable Namespace panel on the main window is unaffected.

Make Channel the single source of truth for a reading's name

2026-09-21T04:30:13Z

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.

Redesign Signal/Channel naming and fix pin-remap breaking references

2026-09-19T23:38:07Z

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).

Channels tab drag-to-reorder, Namespace absolute references, fix stale Channel ID renames

2026-08-13T19:39:25Z

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. Co-Authored-By: Claude Sonnet 5

Fix native-style Qt warning; add a few tooltips; trim Namespace hint text

2026-08-11T16:40:12Z

Root cause of "QFont::setPointSize: Point size <= 0 (-1)" on some dropdowns: the app never sets an explicit widget style, so it defaults to native windowsvista, whose popup code calls setPointSize() on fonts resolved from our QSS's pixel-based font-size (pointSize() is -1 by design for px fonts). Tried app.setStyle("Fusion") first — silences it, but Fusion doesn't render buttons/dropdowns to match the QSS the way the native style does. Kept native style, filtered just that one message via qInstallMessageHandler instead — it's cosmetic Qt console noise (the rejected setPointSize call is a no-op, doesn't affect rendering), not a real bug. Also adds a handful of tooltips (Control Editor's Check Syntax/Cancel/ Create Control, device Configure dialog's Close, main toolbar's View/ Configure/RUN/LOG/Settings, a few Control Panel widgets) from an in-progress app-wide tooltip pass, paused partway through by request — remaining buttons are being done manually.

Add dockable Namespace panel — live Python-namespace browser

2026-08-10T22:45:37Z

New right-docked panel (mirrors Control Panel's dock, opposite side) listing every Signal, Channel, and shared `vars` key currently in the profile, with live values and a double-click-to-copy reference snippet (vars.get(...) / channels.get(...)) for use in scripts. Closed by default — opt-in config tool, no collapse-strip nag like Control Panel gets since it's not needed mid-run. Also moves Configuration out of the View menu into its own toolbar button, and makes table row hover match the selection highlight color. Co-Authored-By: Claude Sonnet 5
