I was thinking about the possibility to add a Full-Screen mode since I can see there are some areas on the pencil2D active screen that could be hidden for allowing more space for the canvas

For instance the upper bar showing the version of pencil and the main bar information could be hidden. To still use the information given by the upper bar (the "*" sign for changes already made) it can be moved else where.

At the bottom of the screen, there is at least one line that can be improved and hidden: the "Zoom: %" information takes a whole line unnecessary. It can be added to, for instance, next to the "Zoom" box bar information on the timeline allowing more space at the bottom
