Resizing your Design Area display lets you customise the workspace to your liking, whether or not you like a bigger or smaller view. This may be significantly helpful when you’ve got a number of home windows or packages open and have to optimize your display area.
To resize your Design Area display, merely hover your mouse over the sting of the window till you see a double-headed arrow. Then, click on and drag the sting to the specified dimension. You too can use the keyboard shortcuts Ctrl + and Ctrl – to zoom out and in, respectively.
