the toolbar looks great..i dont understand what the square icon does..and maybe there are too many icons and little space for each one, for a thumb to tap for example.. if you quit on the "arrow down" icon, the toolbar coud dissapear by timeout or by tapping once outside the toolbar..also the side arrows are redundant and dont offer more function..and i still believe that instead of tapping in the bottom of the screen to the toolbar appearence, it would be better to use the swipe up gesture...anyway..great work!
edit-also the rotate icon in landscape has malfunction, as it hanges to the next pi instead of rotating the present one.
