Mac: We're fans of Jumpshare because it makes sharing files as easy as dragging and dropping them, and today they have updated the Mac version of the app with a slew of new features, including support for screencasts, screenshots, notes, and a ton more.
Unlike something like Dropbox, Jumpshare is more about quickly sharing files without worrying worrying about linking accounts or permissions. Now, the app includes built-in tools to create screencasts, add notes, annotate screenshots, and a few other minor tweaks. The new integrations should clear up your workflow and make things a little smoother.
