This addon was not originally built by me. The original addon was KeyBooster built by Tipsy13. The link to the original is https://mods.curse.com/addons/wow/254158-keybooster.
Patch 7.2 appears to have broken his/her addon and hasn't updated it in a few weeks so I figured I'd fix it and let others enjoy the fix as well. Let me know if you notice any issues I didn't fix.
-I also modified the appearance slightly based on what I liked, such as shortening the Keystone names in the LFG window with abbreviations.
