tbh I find Keyboard Maestro invaluable, I’d say is my top app in terms of value and efficiency, best $40 I’ve spent on an app.
It will not only be useful for DT, but also for any other stuff you regularly do on a Mac, ie any laborious task or repetitive stuff.
You’ll find new ways to optimize and shave a couple minutes here and there.
Also pretty good to avoid using your mouse too much.
Learning curve: Not that hard to learn, you drag blocks in the interface, similar to Automator, and can avoid writing any scripts for many/most of the tasks.
As mentioned, try it but avoid getting distracted by it .
They also have a forum, there you can ask questions too.
