I must've missed this, I'm sure you already answered:
I find myself not wanting to play any of my other toons because the UI is all jacked up and I can't get it to look like GarUI for my main. If I change anything on an alt in Bartender, for example, I find it's been changed on my main next time I log in. How do I get the beautiful UI to work for all my toons? Will it work for non-Hunters?
Just noticed that even with everything disabled, then Bartender turned on, for an alt, I still get the hotbars in the default Bliz UI look, with the gargoyles at either end, stuck to the bottom of the window. >.<
Best way to config the UI for your other toons is to:
- Configure the UI just how you like it on your main.
- Copy your main's folder, paste it then rename it to the name of one of your alts. (Directory is: WTF/Account/ACCOUNTNAME/YourServer/)
- Log in with your alt.
- Type in: /reflux switch GarUI
- Make any changes you want, e.g., bartender bars, keybinds, etc... then save the changes as a new profile within the addon.
I have my other toons configured this way and it works flawlessly. For the most part, I keep everything the same apart from the buff/debuff filters and notifications in Raven, as well as a few bartender settings, such as keybinds and stance bars. Once I change something in bartender, I just save that profile in /bt4 with a unique name for my alt - same with Raven.
By copying the dialed-in character folder, you're able to replicate all of the settings - even for addons like Bagnon that don't have profiles.
You'll have to manually delete the Power Auras, but that just takes a sec.
Hopefully this made sense and helps you out with things. 
P.S. Sorry I haven't been on MG much at all these days. Been so busy I've not been on much period, but I would like to hop on and say hello soon.
Awesomeness, thanks Gar!
Once I get my alts' UIs cleaned up I'll be happily playing a bit more again
