I have forked Asset-Flinger and updated to some long awaited features in Version 0.3:
- Thumbnails are automatically generated on export.
- UI is now changed depending on the chosen blender theme.
- If more assets are available than there is space to show them, the mouse wheel can be used to scroll through.
- The primary data exchange format is .blend instead of .obj, so materials, modifiers and other settings are preserved. Even curves and other non mesh data should work (extensive testing required).
Testers are very welcome!
