I just wanted to announce that macro sets are now in. You can swap between your main macro set and a secondary macro set. This is editable in your macros menu.
The macros can be swapped using CTRL-TAB, /mtab, or in the macros menu. Make sure you save before swapping tabs when editing them!
This should allow you to have two macro sets per character, for example, a PVE macro tab, and a PVP macro tab. This also includes your macro macros too! Right now this only allows one additional macro set, and when you login you will always default to macro set 1. In the future with the new client we may allow more.
