Please add a full screen option
I think the full screen option already exists.
If you're on a Windows machine, look in the
upper right corner of the Foldit client.
Mine has 3 boxes: _  and X.
_ minimizes Foldit,
 makes Foldit fill the screen, and
X quits Foldit.
Does this solve your problem?
If not, please give more info
to clarify what you want.
