Just an annoying thing, for me, but maybe there is someone out there who is just like me

When I use the browser I normally do it in full-screen mode.
To close the browser I normally click the hw min-max button to get the 'x' in the upper corner to show so that I can close the browser.

Now I know I have two more options: ctrl-w and using the pull-down menu (either from the hw key or by holding the stylus against the screen for a bit) - but still, I dont particularly care for either option.

What I would really like is either;
A) an icon on the toolbar for closing the browser, or
B) a way to configure stylus-sweeps to be commmans (the was Mauku allows you to close, etc just by drawing a simple figure/letter on the screen.

'A' I assume would require a change in the actual browser (or maybe a plug-in),
but 'B' made me think- Would it be possible to create an application independent program that would allow you to, in this example, CLOSE, the current app/window you are in by a defined stylus stroke?
