One frustration I've had with Mac OS is window management, particularly the need to resize windows to the way I want them when I attach my Macbook Air to my external monitor. Today I learned about Moom and I have installed it to try it out. Looks like Moom has a lot of features, but all I want to do is save the windows as I have them and then be able to invoke the configuration when I want. Can't believe I have to buy an app to do this as this should be built-in. I know Windows has the same problem but at least I Microsoft provides Powertoys. #
