Ok, I've managed to replace all my DART textures now, only problem is that I had a couple of them set to display using events in DART, one anchored to the castbar so it'd only show when the castbar was visible, and one set to only show when I had a target selected, is there any way to replicate this setup, with Visor if required?
Here's my new UI with UI scale set to minimum as per your suggestions. Please keep in mind this is for a healing paladin during raids. Outside of raids PerfectRaid and oRA MainTankFrames on the left aren't visible, nor is XRaidStatus on the right above the minimap. ag_UF party frames sit below my player frame in 5-man parties with the ABF style and mana bar hidden (so takes up about as much space as group 1 in PerfectRaid). I may move Squishy down and find someplace else for XRS.
