Thanks for so much information!
Out of all the things mentioned as possible in that post, this is the one I'd most like to see displayed more prominently and more constantly.
Yeah, I know "more constantly" sounds weird. I can't think of any other way to express the thought. I'd like to see that information all the time without any need to bring up a menu or hit a recast macro.
To avoid clutter, the recast for abilities that are ready to be used could vanish.
