Thank you both for the replies. Alas, my memory has its limits- I have a lot of keybinds, and certainly, have memorized and used tricks to remember a lot. Of course, 1to= are my full rotation, so I remember that, (mostly,) and I use H for healing, F’s my glider, \ are all mount/dismounts. But I’ve also got a ton of toy/trinket/bomb/fishing/crafting etc binds. It’s a lot, I know, and not for everyone.
Your suggestion is actually one I could absolutely implement, just by creating my own button icons with large visible binds, then using them as blank macros and applying them in fully transparent bars with click-through, on top of my regular bars, using either ButtonForge or Barternder 4. Would be a bit labor-intensive, but certainly an option I’ll consider! Thanks again! (Still hoping someone offers up an add-on, since I’m way too confused by programming my own WeakAura.)
Minor necro, in case anyone comes across this looking for a solution to the same problem: ButtonForge did not hear my pleas, but Bartender4 did! With BT4, you can now pick your keybind font, choose its color, as well as its location on the hotkey, AND scale it to your heart’s content. Problem Solved.
