I am often in areas without a wifi (I use an iPod Touch) and would like a really simple overview page tucked away somewhere.. maybe in the the settings tab, down by 'About Mantis'.
Just a quick way to learn about different features of the program. Many of the features are becoming so rich and for a new user can be a bit difficult to find all of them (especially with the hidden corners). Something someone could scroll through to read about what they can do with Mantis...
Just a thought.
