It was brought to my attention (no idea why) that Dominos has enabled the extra bars (MultiBar5-7) in classic. However you cannot bind keys to these bars because the bindings don't exist.

Dominos can add the missing bindings by uncommenting in Bindings.xml and editing button.classic.lua to not use MULTIACTIONBAR5BUTTON, MULTIACTIONBAR6BUTTON, MULTIACTIONBAR7BUTTON

For now, you can use quick binding on these (/kb). I added them because I noticed that they were usable in classic.

The bars exist, but you cannot bind anything at all. The the button commands dont exist.
