Keyboard Maestro allows you to simplify or automate nearly any task. No words here can capture its capabilities. Additional perks are its stability, no subscriptions (and discounted upgrade pricing for existing users), and a helpful support forum.
For everyone recommending Rectangle, for instance... I just have a few Keyboard Maestro macros. KM probably replaces half a dozen other apps for me.
For someone using neither of these tools yet, Keyboard Maestro is probably the nicer one to start with to give you a taste for how useful some of those automations can be!
Both are pretty powerful.
I do miss it's simplicity in pulling info from the system.
Want to script actions in an app that isn't easily scriptable? It's got your back.
