Thanks for the tip. It does part of what I want, resizing to specified sizes, but it doesn't appear to position windows. Here's an example; On my desktop, I have gridlines setup that allow me to maximize a text editor to use the full left half of the screen with two terminal windows tiled veritically on the right half of the screen in about a 75% / 25% split, with the bigger window on top. To achieve this, I just open the windows, move them to the right area of the screen, and alt + click on the maximize button.
I'm looking for something similar to that without nView.
EDIT: Looking at Sizer some more, I think I might be able to get it to do what I want after all, it'll just be a little more work than with nView. Thanks again for the tip, I think it'll work out.
