Branding:
- Rename app, window title, file extension (.labdaq → .labui), user data
dirs (~/.labui/), spec file (labdaq.spec → labui.spec), and APP_NAME
throughout all source, docs, and config files
Plugin system:
- Plugins no longer bundled in the PyInstaller build — installed at
runtime by users via Settings → Plugins → Install Plugin (zip)
- PluginManager now takes user_dir + extra_scan_dirs; user plugins live
in ~/.labui/plugins/, dev scan additionally covers project plugins/
- install_from_zip / uninstall / is_user_installed added to PluginManager
- vendor/ dir inside plugin zips: prepended to sys.path at load time so
plugins can ship their own deps without requiring pip on end-user machine
- source_url field in manifest.json: shown as Download button in the
missing-plugins dialog when a profile requires an absent plugin
- Frozen-app pip install now targets ~/.labui/plugin_packages/ using a
real system Python (sys.executable is the exe in frozen builds)
Profile loading:
- Profile now stores plugins_manifest snapshot (id, name, version,
source_url) alongside plugins_enabled
- On load, missing or dep-broken plugins trigger MissingPluginsDialog
before the rest of the profile is applied; user can install from zip
or download via source_url in-dialog, or cancel the load
- Plugin reconciliation only enables installed plugins — missing ones
are not written to enabled.json
UI:
- Version label added to status bar (bottom-right, muted colour)
- Settings → Plugins tab: Install Plugin… button, per-plugin Remove
button for user-installed plugins, live list refresh after install/remove
Docs:
- New docs/building.md covers the full release pipeline
- docs/plugin-development.md updated for new install flow, vendoring,
source_url, profile behaviour, and distribution instructions

Run/Stop previously only paused acquisition — control outputs (motor
speed, switches, PWM duty) kept whatever value was last written, so
stopping the run loop didn't stop a running motor. Adds
ControlWidget.safe_stop() (per-widget override, default zeros the
output) and ControlPanel.safe_stop_all(), called from _toggle_run's
Stop branch before engine.stop().
Per-widget behavior is deliberately not uniform:
- OnOffSwitch/MotorControl/PwmControl have a latched running/enabled
state, so safe_stop() drives their own toggle handler (consistent UI
+ write in one path) and, for Motor/PWM, zeroes the slider too.
- SetpointControl/AnalogOutputControl only write on an explicit user
action and have no universally safe forced value (e.g. 0 isn't
necessarily "off" for an arbitrary process setpoint or analog
output) — Stop leaves them untouched rather than guessing.
Log button: added a :disabled QSS rule so "can't log yet" reads as
clearly inert rather than a duller version of the enabled look, and a
600ms blink (toggling a "recording" dynamic property the QSS keys off)
while a recording is active, so it reads as live/recording rather than
a static pressed button. Master Stop now calls _toggle_log(False)
explicitly when forcing the button off, since QPushButton.setChecked()
doesn't emit clicked — without this the blink would keep running after
a master Stop even though logging itself already halted via
engine.stop()'s internal stop_logging() call.

Replace layout radio buttons (Stacked/Side-by-Side/Grid) with a visual
LayoutCanvas widget. Pane tiles snap to grid cells on drag-drop; dropping
on an occupied cell swaps positions. Ghost highlight shows snap target
during drag.
- PaneSpec gains row/col fields (None = unassigned; backward compat preserved)
- LayoutConfig gains "free" mode; strip_chart reads explicit positions
- PaneBlock loses ▲▼ move buttons; reordering is canvas-only
- QSS entries added for layoutTile, layoutTileDragging, layoutCanvasBar
