When visiting a question that has flags, those show up in a popin at the bottom of the screen:
I like this feature a lot. However, there is a curious separation: I can dismiss the flag in the popin, but not act on it. For closing or deleting the question, I have to use the buttons in the flag list or the "flagless" links directly beneath the question.
I propose to include all buttons in the popin. That would make for a more consistent experience (with the flag list) and would allow to act on the flag after having read the question and (then) the flag comment without having to go back to the question (which might include scrolling).
