Working with multiple monitors and can’t get your windows to line up with the edges of them very well? I use AllSnap to do this for me. It makes the edges of all windows and monitors sticky so as you drag the border of a window to resize it, when you get close to another window or screen edge, it will stick to it, making easy to line things up. This also works very nicely when Window’s default tiling of windows doesn’t leave you with an arrangement you like, just do it yourself and leave a narrow sliver for one window, and make the other take up the whole screen.
