There seem to be quite a few features on the site that rely on asynchronous requests to fetch data (paging through queue/my words, waiting for search results, etc), some of which can take some time, especially when the site is slow. Whenever I need to wait for something like this without any indication that its actually doing something I get antsy, second-guess whether I clicked it or not and end up clicking again (maybe making things worse?).
It would certainly ease my mind to have some kind of visual feedback. A simple animation would be fine, just something to say "yes we got you, just hold on until we get a response". Anyone else agree?
