Resize Window

What I'm looking for is a button which, when presses, (re-)maximizes all my windows. With 20+ windows open, after the screen resolution changes, I need to click on each one, restore it, and maximize it again. I hoped this extension would allow me to do this with one click. It doesn't. However, an option like I described would be really useful.

This is useful, however it could be easier to use. Really need a way to set specific sizes or display height&width during resize so I can be more precise. I need to be precise so I can capture at the correct ratio for YouTube, for example.

I love this extension! It really helps me with keeping my windows under control. The only problems that I've found are that it can be quite slow sometimes and that it synchronizes the saved window size between my computers (which have different screen resolutions!).
