Aptonic’s Dropzone 3 ($10) is a pretty handy tool if you’re a Mac power-user who is constantly dragging and dropping files around your Mac and uploading things to online social media and sharing services. The app sits up in your menu bar and pops up with a drop target each time you pick up a file and move it somewhere, making it super easy to copy and move files into folders or applications, or upload and share them to services like Twitter, Facebook, or your own FTP server. Dropzone 3 also adds a new Drop Bar feature that lets you stack up files for later by dropping them on the Drop Zone target where they’ll stay until you either drop them into a Dropzone action, into a Finder folder, or into another app.
