This UI compilation is very memory- and cpu-effective (
screenshot), but it still provides me with everything i need. I also have BigWigs and oRA2 mods turned on in raids, but it's only because of my guild rules.
Some mods of me that i can share:
aMinimap - very simple minimap mod. Features:
- square minimap, 2px border
- every ugly button is hidden
- mousewheel zoom
- tracking button made transparent and moved to bottomleft of minimap
- bg icon moved to bottom of mmap
- mail icon changed & moved (icon from AI-Minimap, many thanks to AI)
Position is changed in aMinimap.lua file, line 8.
aSettings (
mirror) - adds some random tweaks. Features:
- new slash commands: ui reload (/rl), readycheck (/rc), getting the name of frame under cursor (/gn)
- camera distance maxed out, screenshots quality increased (6/10 atm, can be changed at line 18)
- world map scaled to 3/4 and made cleaner (
screenshot)
- UIErrors frame moved up a bit
- Some automation: greed on greens, sell grey items, repair all equipment.
- Every part of code has comments, so you can use only things you need.
oUF_ALZA - custom oUF layout. Screenshots:
