Is there a way to fullscreen or make the tab normal size? On my computer it came up as a small tab that I can not maximize. I can't find if there is a fullscreen control anywhere.
You can do it two ways:
The first way is to click the button in the bottom right that has a checkmark on it. That opens a little window, with options like large screen, full screen, edge mode, etc. Check the fullscreen box. Uncheck it for normal size or large screen.
OR
Press the '~' key on your keyboard. THat will open the TPT console. type kiosk and press enter. To get back to normal size use scale:1
NOTE: If you are using a mac, fullscreen is disabled. At least until the latest version is released.
