This is mostly a performance improvement update that makes it much smoother to deal with large dungeons. You can also create subdirectories for your own icons now, to organize them better.
Changes
- Major performance improvement
- Subcategories for icons (by creating subdirectories)
- Default is now no sheet grid lines
- Fix for miss aligned clicks on HiDPI Macs
- Don't crash when reading unsupported (interlaced) PNGs
