OpenAVC v0.4.0

April 5, 2026

Programmer IDE UX overhaul with concurrent editing safety, real-time feedback, and WCAG accessibility pass.

Concurrent Editing & Real-Time Feedback

Project revision tracking prevents one browser tab from overwriting changes made in another (409 Conflict detection)
Device commands and state changes return success/failure acknowledgments over WebSocket
Macro test runs show per-step results, conditional outcomes, and per-device success/fail for group commands
Human-readable error messages replace Python tracebacks for connection failures, timeouts, and permission errors

Macro & Trigger UX

Copy/paste macro steps across macros
Step templates for common patterns (Volume Ramp, Source Switch, Power Sequence)
Macro dependency tree with circular dependency warning at save time
"Fire Now" button to manually test triggers
Cron field-by-field editor with common schedule examples dropdown
Trigger condition preview showing live true/false evaluation
Event pattern autocomplete for event triggers

UI Builder

Element palette search and hover preview thumbnails
Grid configuration (cols, rows, gap) in the canvas toolbar
Multi-select with common property editing, distribute horizontally/vertically, and context menu
Page thumbnail previews, page type icons, breadcrumb, and "Set as Home Page"
Theme tab in Properties panel with live preview and "Overrides theme" indicator
Asset search, large image upload warning, and unused asset detection

Variables & State

Variable descriptions shown in tooltips and key pickers throughout the IDE
Validation rules for variables (min/max for numbers, allowed values for strings)
Rename variables with automatic reference updates across macros, triggers, UI bindings, and scripts
Bulk delete unused variables
Activity log expanded to 500 entries with per-key filtering

Device Management

Real-time field validation with live ID preview
Filter chips (Online, Offline, Orphaned, Ungrouped) and device count summary
Auto-generated group IDs, group deletion confirmation, and bulk select actions
Discovery scan phase indicators with estimated time and high-confidence match badges

Script Editor

Enhanced autocomplete with return types, parameter types, and examples
Full error tracebacks with clickable line numbers
Script load error icons in the file tree
Macro-to-script conversion preview
New templates (Scheduled Task, Device Monitor, Custom Event Handler, Variable Watcher)

Accessibility (WCAG AA)

Text contrast fixes across muted text
ARIA labels on all icon-only buttons and status indicators
Visible focus outlines on all interactive elements
Semantic tab, list, and dialog markup with proper roles
Keyboard shortcut reference panel (Ctrl+/)
