Why not have the "download" function beside the "share" dropdown. That is where my eye is drawn in the interface. There TWO main functions your site provides and over the years you have moved "download" all over the place.
I understand you want me to stay and share and be in a community or team. But your too main functions in my opinion are to upload and download. Why is the "download" function hidden in the 3 dots in the sub-navigation (secondary)? Downloading from DropBox shouldn't be a secondary function at all. Turn that "close sidebar" symbol the other way and you have a "download" icon. Sometimes you want to "upload" and "download" that's it, get in and get out. I feel as far as the functionality you have missed the mark. Unless of course, you were trying to make me stay longer in frustration, trying to get to the files in my Dropbox.
