Your app is absolutely amazing!
You have a nice feature for a "concentrated reading mode"
That cancel the appearance of the lower tool bar.

But can you please add an option to cancel also the upper system bar
( The android info of time, date etc) - meaning a full screen mode.

A lot of reading apps has this option and it will
be amazing if you can add it.

Please see the 3 pictures I added to this email.

1. Wikipedia full-screen mode - se the remarks on the picture.
2. A full-screen mode using a third party app ( Totally full-screen )
3. The app I used for a Totally full-screen.

Using a third party app isn't that convenient and it has it's bugs.
And the reason I'm asking for the feature is because it's very very very
helpful once you intensity:))
