This is one of those things that I feel like should have been self-explanatory purely on an accessibility level, but for whatever reason it seems to have slipped Blizzard’s mind.
Keybinds in Cooldown Manager!
I used to make my own WeakAuras, then I used Luxthos’s, then Quazii’s, and then I went back to making my own, but no matter which ones I used, I’ve always edited them manually with an additional text field that showed my keybinds. I play a lot of classes and my memory isn’t the best, so this helped a lot with knowing what to press and when — especially when getting used to new specs where I might not be too familiar with the icons themselves.
To be clear, I’m not asking for the ability to click the icons in the Cooldown Manager. This is purely about the visual aspect of it. The way the Cooldown Manager looks currently is little better than having nothing at all. I shouldn’t have to glance down at my action bars constantly to remember what my binds are; your action bars are the back end, the Cooldown Manager is the front end that should neatly display the info you need.
