Excellent - best in class

There are several window snapping apps that seem to be getting a lot of attention, but this app does window snapping plus lots more and does it very well. Highlights include creating keyboard shortcuts for most used window layouts (a feature I use many times a day) and auto-window arrange based upon which external monitor is plugged in. I’m a prof, so the latter comes in handy when on a daily basis I am changing from my external monitor in my office to a projector and back. Each time I plug in the external monitor, Moom automatically arranges the windows to my default setting for the monitor arrangement. This app solves a lot of small daily annoyances.
