How can I easily test Guis in Studio?

I love designing Guis, but when I want to make one that is centered, or stretches full-screen, it takes me several times of Saving, then Playing, then Editing, then repeating the process because of how the Studio layout is.

When the Explorer and Properties, and Toolbox or anything else are opened on Studio, they take of space on the screen, and rather than Studio shrinking the screen size it just lays the Windows over top of it. This makes it so that I can't see Guis underneath it, making it impossible to Center the Gui easily, or make it full screen easily.

How can I get around this? I've been trying to do a Gui, and it's very frustrating.

Well i'd just mess around with where the windows are until you're satisfied with where they are. Whenever you aren't using a window such as tool box close it so you can get more room. For GUI positioning, you can use offset to make the position of the GUI the same on all screens. For example if you wanted to have a GUI that was the same size for every computer monitor you would use offset for sizing.

Example: {0, 100}, {0, 100}

If you wanted the GUI to be in the same position for any computer monitor you would use both scale and offset.

Example (This would make the GUI in the middle of screen no matter what the size of your screen):

{0.5, Gui's offset divided by 2 NEGATIVE}, {0.5, Gui's offset divided by 2 NEGATIVE}

For where it says "Gui's offset divided by 2 NEGATIVE' you would put the GUI's size's offset negative.

Example (If the offset for the gui's size was 100 for both the x and y axis.):

{0.5, -50}, {0.5, -50}
