Implement different colours for different habits
If this is implemented, it should be optional. One reason I chose this app over Productive is that having to choose a colour and icon for each habit adds friction, meaning I would risk adding fewer habits.

I like colours/icons but not essential
I would prefer different colors for different categories
And/or multiple colors per goal where there could be different “levels” of achievement. For example, green for when all my meals were healthy, yellow for when some but not all were healthy, and red for cheat days/fall-off-the-wagon days.
