Sproing! - 1.2.6

Sproing! is an easy to use multi-item launcher, application switcher, and file manager. Sproing! facilitates many day to day computing activities such as: opening documents and applications, switching from one application to another, quitting applications (individually or all at once), browsing folders and disks, moving files, renaming files, deleting files, etc.

You create as many file categories as you want and drag and drop to add items to your categories. No matter how many categories and items you add to Sproing! it never takes up any more screen space.
When you need it, Sproing! It springs into action. When you don't need it, Sproing! It springs out of your way but remains accessable via a small button window that you can place in any convenient location on your screen.
