For reference, I have Bartender4.
I used the gear update feature on a DK alt on a different server. One big problem is that it reset the abilities on my hotbars - some abilities are no longer on my hotbars (I checked the spellbook for reference and some abilities were highlighted as not being on my hotbars) and others were moved to 2 hotbars in a random order.
Can I save ability layouts and copy them between toons of the same class? I just don’t want to have to go through the effort of setting up my abilities again each time I use the gear update on an alt.
