Yeah its not switching keybindings now with page swaps, tis a bit broken hehe.
Keep the bars that you swap enabled, but hidden. That's how I got the keybinds working on swapped bars.
Yeah I am using that as well and got no problems... U Must Enable but Hide the bar that is paged to and apply the same KeyBindings on Both Bars.
Also, A nice feauture I'd like to ask, is to have the Option to keep tha default Blizzard UI so we actually use Bartender as a Complement to Default UI, instead of overall replacement. I had to hack a bit the "OnLoad" code to keep the Default MenuBarFrame and ShapeshiftBar Intact so I Could use It as a COmplement to my UI, rather thna complete change.
