Need Fullscreen mode like Drawboard or Flexcil
As you know, Windows Devices are mostly used in Landscape mode(because of size or Windows was built to use in landscape) but the size of tool bar is so much bigger than the iOS version that the waste of space in landscape mode is too big

Or at least just showing the tool bar without the exit/minimize/zoom info on top. I don't think there's actually a full screen mode in the windows version yet. I think recently there is a full screen mode on the ipad where you can hide the ipad clock and stuff on top of the tool bar. I think the toolbar is kind of necessary but it could be a full screen page view.
