This probably seems minor, but I would like my favorited questions to be marked somehow on the Recent Questions list. I end up reading several titles (of those which aren't being ignored) thinking ``This looks interesting'' only to realize that it's a question I've already looked at! I don't think this is just my problem, perhaps so far, but as the number of questions increases this will certainly happen more frequently, since there are only so many titles to expect.
Relatedly, I don't know how specific to make my titles.
On specificity of titles: I'd really encourage everyone to actually ask a full question in the title! Don't worry if it takes two full lines to do so. And if you "can't" do it, then stop and think for 5 minutes about your question first! :-) The body of the question should be much longer because it contains motivation, background, or partial ideas, not because the title is just a subject area.
Said differently, I'd encourage everyone to not think of it as "Title" and "Question" but as "Question" and "Explanation".
