Maybe I’m weird but I don’t on many characters actually have my first few action bar slots use the 1-5 keys. Mostly because I’m trying to match mentally certain actions with certain binds (consistent across alts) while also grouping similar types of cooldowns together on my bars.
It would be cool if similar to Bartender functionality (although you have to use scripts with BT I think) there were an option to make an action bar only visible while on dragon back and automatically hide itself otherwise (especially if it could re-use / override other binds while mounted).
