Bars 1, 4 are the main bars. Bar 1 for single target damage and single target healing. Bar 4 for multi-target damage and multi-target healing.
I try to keep the same category of ability on the placement between these two bars, so for instance, Regen/Medica II are on the same relative position as they both provide regen. The same with Cure and Cure II versus Medica and Cure III for non-regen heals.

Left Expanded XHB bar is for less frequently used heals with long cooldowns or heals that use a resource like blood lilly. These are also placed on a standard non-XHB bar visible at all times, so I can see their cooldowns even when I don't have it selected. The exlaimation point macro there is an experiment I'm trying which combines swiftcast with an all-classes raise. I've not had a chance to use it yet for all of them, so I keep it there alongside my actual raise ability as a backup.

Note: Sprint and Limit Break should be on a Shared Hotbar!!!

Buttons consistent for similar job actions (Dye = Potion)

The layout I use for my WHM, will most likely change if I run into issues while attempting harder content.

All hotbar keybinds are arranged as follows
1: QERF
2: CV12
3: 345T

I try to play every classes/jobs, thus I tend to reuse same slots for same "functionality" across jobs.

Bar 1 binds are generic, 2 uses [Ctrl]+, 3 uses [Shift]+, 4 uses [Alt]+
