Yeah, it’s interesting to play with apps, then you go back to what you know works. I use a combo of Keyboard Maestro macros and BetterSnapTool to manage window placement and applications as well.
idk if Moom can open or close applications, but KM can do that and more. I like KM for preset apps and windows, and BetterSnapTool for adhoc changes. Don’t forget you have access to Mission control and hot corners, as well. Many people forget those are there.
