streamlined skill strengthening
I recently completed the German tree. Now every day I switch over to it from the language I'm currently learning (Spanish), so I can do enough to to keep my tree gold. I find myself scrolling a lot just to make sure I've no skills left that require strengthening. It would be nice if there was a way to just indicate I need a skill strengthening session and do that until I've none left to do.
I just do the general "Strengthen Skills" button. That works to keep your home page gold, too.
