support; i actually brought smth up similar yesterday on discord and was debating posting on the suggestions forums and i might still since its slightly different & affects a different part of user interactions.
i think your suggestion would be much more flexible and useful than mine, since you could toggle things
per user rather than grouped. in addition, i think the
per-user private notes suggestion would pair nicely with these.
i dont know if its feasible either, but since we've got ids, block lists, friend lists, and user groups, i think something could be worked out.
iirc cs runs on a very old form of phbb; it'd be great if it could one day upgrade so that more qol upgrades could be easily made, but i also know that is a very big thing to do, especially for a completely free-to-play website with only one person working on code.
