This no longer applies:
Okay... so I've got Trinity Bars 2... I see no where that lets me have more macros or extra long macros... where is this feature and how does one access it in game?

TIA for your help.
So I found where you do that but I get an error:
Interface\FrameXML\SecureStateDriver.lua:134: attempt to index field '?' (a nil value)
Soooo... is it borked?
