What's new in Dropbox - 5th Edition

Hey Dropbox team,

Generally awesome update - love the new look and simplicity. I'm frustrated by two things, one of which is already mentioned by others but the other not:

1. The effective screen width has been greatly reduced, due to the new right-column functionality and increased font size. This really doesn't work. Please see what I'm talking about - an actual screenshot in Chrome on a Macbook Air with browser full width. Yikes.

2. About every 3rd navigation click doesn't actually change the view. I'll click a folder, or press the back arrow, and the address bar/URL will update, but the screen will not. This requires me to refresh my screen about 50 times whenever I'm navigating around my Dropbox. I understand you guys were going for a more clever UI system than plain ol' linking, but this is a perfect case where utility should trump cleverness.

Is there a way to revert my version until these bugs are worked out? Since Dropbox is much more a necessary utility than discretionary app for me, I would prefer not to be a guinea pig to new changes. Maybe test it out on 1/10th or 1/100th of your userbase first, without subjecting the rest of us to brittleness.

Thanks,

TOM
