- Checkpoint field in preset editor now opens a file picker filtered to .safetensors
- LoRA field in flake editor now opens a file picker filtered to .safetensors
- Load Existing now opens a file picker filtered to .yaml/.yml
- Each picker attempts to map the selected file name back to the backend's full path
- Manual text entry is still available via a small '...' button next to each picker
Note: Browsers do not allow setting the default directory of a file picker for security reasons.
