we still can't edit forum tags or add multiple of them

on the SP site, we can freely edit the tags of forum posts and even add multiple, but we can't here. for example, if somebody makes a post with a question about a thing that's not completely related to SR2, they can use either the question or the off-topic tag: one or the other, never both.
also, since we can't edit forum tags, the "solved" category (used for marking questions that have been solved, obviously) is basically useless.
i'm guessing this feature was added to the SP site before but devs forgot to add it here, but still, it would be quite useful
