I know there is MoveAnything but it seems to have some problems on the PTR 2.3 and seems not to be supported :(
Then there is Visor/Visor2 GUI - this Addon does it's job on the PTR but only if the frames are visible (for example Unit Frames). I can't move the lower-right tooltips and the warning frame (for example if you are out of range). Is there a possibility to move those frames with visor?
If not - is there another addon which does those jobs?
the warning frame...if you are using Parrot (or any combat text, i think), you could use Error Monster to redirect errors to another frame with the combat text (and since Parrot allows you to create more output frames, that would give you the most flexibility).
