I have been trying to find an addon similar to action bar saver for classic wow but there does not seem to be one. I know this is a long shot but perhaps there is a lua coder here that want to take a shot at making one? I suspect an addon like this would become one of the most used addons in classic.
Some references to what action bar saver actually does:
curseforge. com/wow/addons/action-bar-saver
youtube. com/watch?v=2c3H7O-ZCds - 1min 40sec long
Idk man, i tryed that versione on classic, and when i do /abs restore profile, instead of loading the profile It only load the macro and usabile items i had in the action bars when i created the profile but not a single other spell
