[A suggestion that >hopefully< hasn't been considered yet] (Recommended) ruleset highlights for modes

[Lilithtreasure]

This one might need a bit more explanation. so like, there is no visual indication (or tagline) of like, recommended rulesets for modes; like either the user needs to know beforehand as to what rulesets would go with each game mode, brush up on, or experiment.
a rough mockup of what that could look like:

(shoddy mock up)
in this example, the Marathon A3 mode is selected, with the Ti-ARS and Ti-World rulesets marked in green.

The color of a recommended ruleset should be a different color from yellow (to distinguish it from cursor highlights and selection)

there's probably way better ways of describing/explaining this (maybe like how Nullpomino has recommended rulesets for modes?)

we started thinking of that feature internally (with a general refactoring of mode/ruleset selection), I understand what you mean, and we'll try to implement it in the future (no urgent promises though)

The green color in that menu is used by tags as well, so, it might be a bit confusing without iconography

mmmm, yeah it'd need iconography for sure (hmmm... what if it had iconography, even if not green colored?)

This, or perhaps putting the modes as a submenu directly underneath, similar to how you can indent a bulleted list:

MODE NAME:
  - TI-ARS
  - TI-WORLD

This needs more thought, but thought I would mention.
