BBEdit recently released a nice update (version 14.1) with, among other things, Shortcuts support. You can now create a text document and create a note in BBEdtin from Shortcuts on the Mac. As Mac applications go, BBEdit is one of the standard-bearers. (It was first released in 1992.) I know people that switched to the Mac for the exclusive purpose of using BBEdit.
Seeing apps like BBEdit begin to adopt Shortcuts is a good sign. Granted, the initial Shortcuts actions, relating to file creation only, are not super deep, it’s a beachhead. Talking to Mac app developers, I get the impression that will be the case for many apps. They’ll get some Shortcuts support in and then watch for Apple’s lead before going into deeper waters. I think that is fine. The last attempt at Mac automation for the masses (Automator) never really took off not as a result of any problem with the underlying technology but, in my opinion at least, a lack of enthusiasm from the suits at Apple. That doesn’t seem to be the case this time around and initial signs for Shortcuts and third-party developers are promising.
