Help with window sizing

Hi, this may be very basic but when I launch Pencil the window that I can use to draw on seems pretty small compared to the rest of the client. When in full screen the draw space is maybe 800x600 pixels. I can’t find anyway to resize it to take up all of the space in the client. Help me out here boys.

You should be able to zoom in and out using ctrl+arrow keys, and if you double click on the camera layer you can change the canvas size. You can also put tool boxes and other windows inside of each other to make more room. I hope that helps?

Double clicking camera layer! Thank you.
