Opticon was put together because I wanted a simple solution to accessing various things. It's meant to be used as a launcher because its primary focus is clickyness. And here are the various ways in which you can click it and what they do:
Left Click: Toggles the Blizzard Addons options frame.
Right Click: Toggles the Blizzard Game options frame.
Alt + Click: Opens the Niagara menu (if you have Niagara).
Shift + Click: Reinitialises the graphics renderer*.
Control + Click: Reloads the UI.
I can't get this to work on the PTR (that is true for several, but not all LDB addons). This may have something to do with the Blizzard's options menu being fubar for me (doesn't work for any options). The only options I can configure are those that DON'T use Blizzard's interface.
