The new v3 interface includes a Windows Path UI, which I find useful. In the past, v2 allowed users to open BRU via Windows' context menu (r-click), but BRU would navigate to a NEW path if another folder was selected via context menu while BRU was open. It seems that this is no longer the case, at least for me.
While that feature would be nice to have back, changing BRU's active directory via copying and pasting a path is usable. One thing that would make navigating in this fashion more user friendly would be to automatically select the entire path (in BRU's GUI). In that way, I wouldn't have to select the path in order to paste a new path.
This is a small UI nuisance that I find annoying, but others may not.
