### 🚀 Highlights
## Pre-built Docker Images
No more building from source! Pull directly from GitHub Container Registry:
docker pull ghcr.io/maziggy/bambuddy:latest
- Multi-architecture: linux/amd64 and linux/arm64 (Raspberry Pi 4/5)
- Docker automatically pulls the correct image for your system
- Just docker compose up -d — no --build required
## Printer Controls
New stop and pause/resume buttons on printer cards while printing. Includes confirmation modals to prevent accidental clicks.
## Skip Objects
Skip individual objects during a print without canceling the entire job:
- Skip button appears when printing with 2+ objects
- Preview image with object ID markers to match your printer display
- Requires "Exclude Objects" enabled in slicer
## Spoolman Improvements
- Link Spool: Manually link existing Spoolman spools to AMS trays
- UUID Display: View and copy Bambu Lab spool UUID from AMS hover card
- Sync Feedback: See which spools synced and which were skipped (with reasons)
### ✨ What's New
