Ok... I know HOW to use reflux but i got an issue.. i made my UI and forgot to install reflux to i could load it on other chars >.> is there a way for it to take all the stuff iv done atm and save that to a Reflux? or would it just mess me over big time and have to redo the whole UI agian? Everyone atm (on the addons) is saved on the default save so...
Install Reflux, set up the addons that don't use profiles in it, and then use the /reflux snapshot <newprofilename> command. There's more instructions on this method on the current (or maybe 1 page back?) page of the "Ask It! Interface and Addons" thread.
