After 10 years of development there’s a story behind each design decision I guess
We always thought 3 colors are just enough to prioritize. But we couldn’t decide between bg colors and font colors. Even 10 years ago Checkvist customers had different preferences.
So in the (very) beginning there were 1, 2, 3 keys for the three font colors, and shift-1, shift-2, shift-3 for background colors.
Soon after we’ve realized there were not just English/international keyboards, but also German/Czech ones - where you need the Shift to press any number.
Voile - 1, 2, 3 for font colors, 4, 5, 6 - for background colors.
Now we have a plan to make the colors customizable - you’ll have all 9 keys - and an opportunity to select a color (font or backround) for each number. Something similar to the tag color selection, most probably.
Hope we can release it as soon as possible – but not sooner
