When you go to edit the Show Archive Path (or Media/Model Archive Path) in the Shell, the box to edit the text above the keyboard has never been wide enough to show the whole file name. Can it at least be as wide as the keyboard?
I think since I've spent most of the year installing 3.0 on probably 20+ systems (started beta, new GIO, and then Corona Office @ home) and changing the default location every time, that it's not as big of a problem as I think it is.... but I have never had a full folder structure fit into that tiny box.
