Virtual Button Bar

*Now with unlimited colours*
*ROOT required for full functionality* Menu, Back and Search are rooted-only buttons - all others work on non-rooted devices.

Emulates hardware keys (Home, Menu, Back etc) and overlays them on the screen, on top of all applications. Single-swipe action (see video):
• Choose the number of buttons you want, position them
• Lock Screen animations including Gingerbread-style TV off (requires 2.2)
• Change button function (vol up/down, lock device, expand Notification Bar, Camera, Search)
• Alt-Tab functionality
• Change Button sizes and colour
• Adjustable Transparency
• Separate, independent configurations for portrait and landscape

A fully-featured but time-limited trial is available.

To uninstall: If you've enabled Device Administration for the lockscreen, you need to disable it before uninstalling. Uncheck the permission in-app or go to Settings -> Location and Security -> Select device administrators and uncheck Virtual Button Bar.
