I know me, and many others I know would really, really appreciate a simple mod to remove the tooltips from the 'hotkeys' -- Mine, due to the location of my hotbuttons, cause the tooltip descriptions to cover up my Chat box..
Talk about annoying.. sheesh. I have the delay on max, but that isn't long enough.
I don't want to kill tooltips entirely, because there is alot of use for tooltip information on other things.. I just don't need to know what my spell I've been using for 60 levels does every 15seconds. My mouse invariably hovers over my action hotbuttons more than any other area.. and If I don't 'consciously' move it away in time I'll be typing and bam, its covered up. Argg, so I have to move the mouse, and then backspace what I mistyped usually.
I'm going to try to mess with the transparency, but not too sure what I can do..
Also I found one 'tooltip' ui xml file, and it only has a max-width value of 400. Doesn't seem too helpful.
I'm sure one of you UI guru's can come up with something on this. It doesn't seem like a particularly difficult thing to accomplish. But maybe it is just impossible, not sure.
