You can condense the rows (a bit) with a "use denser view" option in the settings. I have my docs pretty heavily broken out into folders, so it works for me.

My biggest usability complaint is how you land on a long list of all your documents, potentially going back months or years. Like Amazon's "product suggestions" for items I browsed months ago, I find this more annoying than relevant. If they only initially showed me documents I've opened in the last month, I think it would be an example of "less is more".
