# Pending Features & Issues
Priority: `P1` quick win · `P2` moderate · `P3` large effort
## Processing Pipeline
- [ ] `P1` **Zone grouping** — Merge adjacent LEDs into logical groups sharing one averaged color
- Complexity: medium — doesn't fit the PP filter model (operates on extracted LED colors, not images); needs a new param on calibration/color-strip-source config + PixelMapper changes
- Impact: high — smooths out single-LED noise, visually cleaner ambilight on sparse strips
- [ ] `P3` **Transition effects** — Crossfade, wipe, or dissolve between sources/profiles instead of instant cut
- Complexity: large — requires a new transition layer concept in ProcessorManager; must blend two live streams simultaneously during switch, coordinating start/stop timing
- Impact: medium — polishes profile switching UX but ambient lighting rarely switches sources frequently
## Output Targets
- [ ] `P2` **Art-Net / sACN (E1.31)** — Stage/theatrical lighting protocols, DMX controllers
- Complexity: medium — UDP-based protocols with well-documented specs; similar architecture to DDP client; needs DMX universe/channel mapping UI
- Impact: medium — opens stage/theatrical use case, niche but differentiating
## Automation & Integration
- [ ] `P2` **Webhook/MQTT trigger** — Let external systems activate profiles without HA integration
- Complexity: low-medium — webhook: simple FastAPI endpoint calling SceneActivator; MQTT: add `asyncio-mqtt` dependency + subscription loop
- Impact: high — key integration point for home automation users without Home Assistant
## Multi-Display
- [ ] `P2` **Investigate multimonitor support** — Research and plan support for multi-monitor setups
- Complexity: research — audit DXGI/MSS capture engine's display enumeration; test with 2+ monitors; identify gaps in calibration UI (per-display config)
- Impact: high — many users have multi-monitor setups; prerequisite for multi-display unification
- [ ] `P3` **Multi-display unification** — Treat 2-3 monitors as single virtual display for seamless ambilight
- Complexity: large — virtual display abstraction stitching multiple captures; edge-matching calibration between monitors; significant UI changes
- Impact: high — flagship feature for multi-monitor users, but depends on investigation results
## Capture Engines
- [ ] `P3` **SCRCPY capture engine** — Implement SCRCPY-based screen capture for Android devices
- Complexity: large — external dependency on scrcpy binary; need to manage subprocess lifecycle, parse video stream (ffmpeg/AV pipe), handle device connect/disconnect
- Impact: medium — enables phone screen mirroring to ambient lighting; appeals to mobile gaming use case
## Code Health
- [ ] `P1` **"Start All" targets button** — "Stop All" exists but "Start All" is missing
- [ ] `P2` **Manual backup trigger endpoint**`POST /system/auto-backup/trigger` (~5 lines)
- [ ] `P2` **Scene snapshot should capture device brightness**`software_brightness` not saved/restored
- [ ] `P2` **Distinguish "crashed" vs "stopped" in dashboard**`metrics.last_error` is already populated
- [ ] `P3` **Home Assistant MQTT discovery** — publish auto-discovery payloads; MQTT infra already exists
- [ ] `P3` **CSS source import/export** — share individual sources without full config backup
## UX
- [ ] `P1` **Collapse dashboard running target stats** — Show only FPS chart by default; uptime, errors, and pipeline timings in an expandable section collapsed by default
- [ ] `P1` **Review new CSS types (Daylight & Candlelight)** — End-to-end review: create via UI, assign to targets, verify LED rendering, check edge cases (0 candles, extreme latitude, real-time toggle)
- [ ] `P1` **Daylight brightness value source** — New value source type that reports a 0255 brightness level based on daylight cycle time (real-time or simulated), reusing the daylight LUT logic
- [ ] `P1` **Tags input: move under name, remove hint/title** — Move the tags chip input directly below the name field in all entity editor modals; remove the hint toggle and section title for a cleaner layout
- [ ] `P1` **IconSelect grid overflow & scroll jump** — Expandable icon grid sometimes renders outside the visible viewport; opening it causes the modal/page to jump scroll
