I’ve been using Broker_Equipment for many, many years now. It hasn’t been updated for a while but still works.
Unfortunately the author has archived the addon on Github so I’m not expecting any updates.
@yellowfive it has the drop-down menu implemented so you could look at that, p3lim is still active with other addons he’s made.
I don’t use the AMR addon for changing gear or specs other than after importing it and updating the sets.
I use the default equipment manager to assign a gear set to a spec and change specs via the default interface knowing that the gear will be swapped for me.
While I understand your desire to have it automated @einistein it’s more complicated than just clicking a button. Do you want it to automatically use a Tome of the Still Mind if you aren’t in a rest area? I’m not even sure if that would work with one button press, possibly if you’re in a rest area but using a consumable too might not be possible.
