This is very likely a tweak of one of Squintina's WHM layouts - I was heavily influenced by her when I started playing WHM. I have changed some things to better suit my style. Updated for 7.0.

The Dye icon on hotbar 3 is Eurekan Potion, as I sometimes do play WHM in Eureka.

BLOOD FOR THE BLOOD LILY

Buttons consistent for similar job actions (Dye = Potion)

Macro 0: Asylum <me>

Macro1: Liturgy of the Bell <me>

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.
