[Idea] Interactive state diagram to setup state groups

[thingnotok]

Now that obsidian has canvas, the state diagram can be converted to/from a canvas page. In that way, I can avoid using text area to config states. the discussion and diagram in #12 can be a good start point.

• [ ] convert current setting to a canvas page
• [ ] verify if a canvas can be converted to setting
• [ ] compile the errors as message to help debug
• [ ] convert canvas to setting
• [ ] how to express command and hotkey in canvas (color, text, ... )
