I am a graphic person as well and i love the control i have over my consumables. one thing i hate is how every option seems to use a slider, i like pricise adjustments (I like to type in the numbers :P). At least i have visor so i can scale it to look exactly like my other buttons hehe.
At first i thought RP was just way too geeky but then my brother started playing on a RP server so to spend time with him I moved too. Well needless to say I'm hooked (and strangely finding I love playing a female tauren druid, oh my therapist is gonna love that one). I just wish he wouldnt have picked a RPPvP server but oh well I have gotten used to gnome slaughter :P. I play on Maelstrom as, you guessed it, Greywind a lovely little (for a tauren anyway) furry druid :D.
Hmm i sort of sounded a little grumpy in my post. I do use visor to move/hide and all around tweak my layout, its just that i really really love the previews. I guess thats why i have a hard time with the xml parts of an addon, im very visual and i have a hard time visualising the placement of the frames in code >.<.
