Although there is an existing paid-app that automatically hides the taskbar in tablet mode, I wished for more functionalities. In particular, I want the taskbar to hide in landscape mode where vertical space is precious, but not in portrait mode where there is plenty of vertical space. I ended up writing a little application to get what I need.

Features of the application:

• Auto-hide taskbar can be turned on or off independently for each combination of tablet mode and screen orientation.
• Install for all users.
• Free and open source.

The application can be downloaded here: http://ticoneva.com/software/
