Fullscreen aka horribly-stretched-mode? Check the game's options if you want it to be in the normal game.
I don't think it's possible in the editor without just dragging the borders of the level window all over the place.
If you mean making your sections bigger, the Level Settings tab in the Editor will help you. You should be able to see a "Level Borders" box in which you can select the direction in which you want to expand your section. Then you move around with cursor and arrow keys and left-click where you want the section to stop.
