Check the spell in /cmc cfg to hide it, uncheck it to show it!
In the Rearrange tab, click the left or right arrows to move the spell as you wish.
You can find the spell ID in the URL of the spell on Wowhead, or by mousing over a spell in game (I have the spell ID showing in your tooltip by default included in the addon)
EXAMPLE: https://www.wowhead.com/spell=206930/heart-strike
the "206930" is what you'll type in to hide Heart Strike from your bar if you're playing a Death Knight.
Please report any bugs you encounter, but also request new features! I will continue to improve the addon and add features.
This is my first WoW addon after playing since 2004. I appreciate you trying this out!
Thanks,
