You can maintain two sets of BLU bars by hiding one set on share or on another class.
All bar numbers have a version for each class, each job, and share, regardless of the share setting for the bar. So if you're not sharing bars 1-4, you can invisibly store bar data to share 1 - share 4 and swap it to blu 1 - blu 4 via macro. If you are sharing bars 7-10, you can invisibly store bar data to blu 7 - blu 10, or arc 7 - arc 10, or any class/job 7-10.
Example of swapping three hotbars by storing them on the shared bars of the same numbers (not sharing 1-4):
Code:
/hotbar copy blu 1 share 4
/hotbar copy share 1 blu 1
/hotbar copy share 4 share 1
/hotbar copy blu 2 share 4
/hotbar copy share 2 blu 2
/hotbar copy share 4 share 2
/hotbar copy blu 3 share 4
/hotbar copy share 3 blu 3
/hotbar copy share 4 share 3
Another example, swapping bars by employing unused bars hidden by share bars (sharing 7-10):
Code:
/hotbar copy blu 1 blu 10
/hotbar copy blu 7 blu 1
/hotbar copy blu 10 blu 7
/hotbar copy blu 2 blu 10
/hotbar copy blu 8 blu 2
/hotbar copy blu 10 blu 8
/hotbar copy blu 3 blu 10
/hotbar copy blu 9 blu 3
/hotbar copy blu 10 blu 9
Either of these macros can be used as a toggle to swap between two sets of bars.
