Colour-coding grammar patterns (for Russian, etc.)

Would love a feature to colour-code grammar forms — super helpful for learning Russian cases!

Example setup:

Masculine - blue

Feminine - pink

Neuter - green

Plural - yellow

And maybe even different shades for accusative animate vs inanimate.
You could keep the same colours across all cases (nominative, genitive, etc.) while focusing on one case at a time.
It’d make patterns so much easier to spot and remember visually.
