Currently, when using the "paste image here" functionality of the new image upload dialog, there is zero indication that something is going on. I click a button. The button doesn't respond, and no part of the page changes. I can't tell if I've screwed up, or if the page has hanged (this leads to me incessantly clicking the upload button). I just have to wait and see if an upload does happen. I've gotten used to it, but somehow this seems like bad UX to me (I wonder what the experts think). A user should get some sort of indication that the computer is listening.
Compare this with the indication given by the new upload dialog when you upload a link:
Even better, the old image upload dialog, where there's no doubt that the system is listening:
Could this be fixed so that there is some indication of an upload for the paste-to-upload? Preferably one of those spinning things or the standard StackExchange "dots" progress indicator.
