Several features that would help alot.

After using Pyxel Edit for about a week, I have some feature requests that I think would help out ALOT.
- Groups/Folders for layers and ability to turn a group on/off
- Ruler and Guides like that used in photoshop.
- Separate ruler measurements for each tile
- Ability to not only import swatches but to add your swatch to the preset swatches so you don't have to import it for multiple projects
- Circle tool/generator
- Circle selection tool
- Ability to assign your own hotkeys
- Along with pixel grid, custom grid that you set size of(right now I have just been using tiles to do this)
I think all of these features would be super helpful and make this program even better. Keep up the great work!
