Window resizing seems to work so far in 3.1, which is lovely. Makes it easier to see very deep tree locations for selective syncing.
A related issue: the InSync UI forgets what you were looking at in the tree view when you change tabs to another drive or the Feed or even the prefs / about tabs.
Oddly, the UI does not forget your location if you close it entirely and open it up again, so the state must be retained somewhere?
Very sad to constantly go from this:
When you want to check an error on the Feed, then have to crawl your way back again repeatedly.
