Another I'd like to suggest is the utter fail on the original RoM action bars is the gap between the buttons. Anyway to close or fill them and do the same with yours? I tend to click between sometimes and loose target.
I also noticed one other things with ExtraActionBars is that you can't add item set skills to it, nor can you return buttons you accidentally lift and swap with RoM action bar buttons. They have to be pulled from the skills pages again which is impossible to do in battle. Items in Item Sop bag can't be added either.
I also use rage pots for my warrior/rogue and found that after a few uses the buttons stopped working even though I still had more pots.
Also things that require the build up of rage do not change with rage. Example being a skill that requires 15 rage is already lit up with zero rage yet obviously can't be used.
I hope this information is useful.
