What level of user interface customisation does Rift support? Is it possible to move/resize/remove individual user interface elements?
Does Rift support addons, similar to the way that World of Warcraft does? I am intending to go down the familiar route of being the group/raid healer/support character so some kind of mouse over healing addon (similar to VuhDo or Grid) would be ideal.
Whilst Rift doesn't have as many community developed addons as the big fish like wow etc, it does have a nice tidy pack of customization and enhancement options provided via third party users that seem to (at first glace, I haven't utilized these myself) mimic the best UI addons from other similar games.
Healing frames happens to be one of the most popular. (MereHealingFrames)
