When I write a comment or anything in Bugzilla and hit the SUBMIT BUG or SAVE CHANGES result, there is no visual feedback of any sort at the place where the action takes place (the button). As a consequence, I repeatedly send comments *several* times, which is very annoying for every one.
I can see a very tiny but of feedback, the text of the button moves by what appears to be 1px right on mouse-down, though I cant seem to find any particular CSS that declares any particular attributes. I agree this could be better / more obvious. I can think of a couple of things: 1) Disable the button on click. Might cause issues with network issues or request timeouts. 2) Modify the knob-buttons class to make action more obvious. 3) Add some text, ellipses, progress animation onClick(). These will need timeout/response handlers so they correctly reflect the state of the request. @Michael What kind of feedback were you thinking?
(In reply to Kubilay Kocak from comment #1) I'm certainly not the best person to make a qualified answer to this. However I think a simple reaction of the button (bumped -> sunken for instance) would give a visual cue that something happened.
My mistake (sorry): reduced severity for a feature.
