I often tile my windows. I also often find that I don't want to split the windows right down the middle. Perhaps I'd like one window to take up 5/8ths of the screen and other windows to divide the remaining half.
It's easy enough to create such a layout with a program like GridMove (which I already use). However, resizing your windows on the fly is time consuming because you have to resize every window that is currently visible.
I'm looking for a solution that would let me resize one window and the other automatically resizes (akin to resizable separators).
Here's an image of what this would look like:
Initially, I have my windows located like so (the red line shows the divide between the windows I am going to resize):
I want to be able to drag the left side of the Firefox window with the other windows adjusting in size accordingly:
In fact, the particular combination of Windows that are open shows a particularly common use case: the website I am viewing (this one) does not display properly on narrower resolutions, so I'd have to resize the window in order to view the entire site.
Is there a program that would allow this kind of resizing?
