The XHB setup I use for my Armorer. 1-3 are unique to ARM, all else are shared between all jobs. XHB4's LT->RT pane is a selection of emotes. XHB7 is my job selector.

Layout for all my crafters. Ignore bar 4 or throw them on another bar somewhere. It's just specialist actions. Room for 4 macros on Bar 3

The idea for my DoH setups is that there is a main hotbar for the most common crafting rotation actions (for 80+), you press R1 to access all other quality, progress and misc. actions, and the middle hotbar is for crafting macros plus Specialist actions. "8", "4", "7" and "3" are for 80, 40, 70 and 35 Durability respectively. With the gold colour macros being 2 steps
