- Unit conversion for 3D printing (millimetres, centimetres, metres, inches)
- Supports .gltf files with separate .bin and texture files
- Drops materials, textures and animations as STL cannot store them
- Expands mesh instances to separate triangle copies
| - Two-way synchronization with filesystem event detection and periodic scans
- SSH private keys stored locally on each device, never sent to servers
- Conflict resolution by keeping both file versions
