Dropbox has just announced that they now have an indexed search box that finds results as you type. The file-sharing service also added picture thumbnails, drag-and-drop, and keyboard shortcuts for selecting files. Dropbox revamped their website to include right-click functionality for downloading, renaming, and moving files.
A few of the problems that Dropbox has is that file sizes and folder sizes are not viewable. If you use Dropbox to share and edit files with others, only their first names show up next to the file that has been edited. If you work with two people that have the same name, then you will probably find this inconvenient.
