Multi-colored cells

[billbauman]

Could you add the ability to maybe ctrl-shift click or something like that to multi-color a cell instead of changing it from one monochrome selection to another? That was I could have like 6 is red, and 7 is orange, so I could red/orange a cell and know it's only one of those two options.

I'm working on this. No guarantees on when a PR is ready 😉. You can view the progress in my fork: https://github.com/JJK96/sudoku-web-app. Current status: highlighting of pencilmarks is implemented. The color can be selected in the color picker by holding down a color. Then the color can be applied to a pencilmark using the pencilmarks tab.

TODO:

• Implement highlighting of pencilmarks instead of cells
  • SImple marks
  • Inner/outer marks
• Fix highlighting of full cells which I broke somehow
• Implement user interface (VirtualKeyboard) to select the color of the next pencilmark
• Fix touch (notes are highlighted black by default and hold does not work)
• Make button hold duration a setting
• Test if nothing else is broken
