Personally I think we should just get full on god mode when editing houses. The lack of "flying" makes precise adjustments high up difficult to do. The rolling and character run speed are also difficult to deal with (I go into walk mode to edit).
The best way to address that is ... using /bug ingame and tell ZOs!
The more do that the more attention it will draw to them and make them implement a fix, a setting or at least API so addons can help
