This seems like a recent change to how Dropbox works on Chrome on a Mac - whenever I upload a file, the +Upload button disappears, and I must refresh the browser in order to get it back. I routinely upload multiple files in a row, where the files are from many different sources, so I can't just select the bunch and upload them at once. I would REALLY like to change this behavior, and have the +Upload button available at all times. Thank you in advance Dropbox team! I hope I'm not just missing a setting somewhere where this can be changed, but I looked around and couldn't find anything that would restore having the +Upload button always available.
