Typically in Windows 7 and on, when you drag a window to the side of the screen, it will "snap" its size to automatically take up half of the screen. For example, you can snap the logic analyzer to the window to the left, and a datasheet or schematic to the right, and they will each take up half the screen.
Also, dragging the window to the top of the screen automatically maximizes it. As someone used to working with windows like this, I'd like the Salae windows to behave this way too. I'm not sure why they don't but I am assuming it has something to do with the cross-platform aspect of the software.
