Would be very handy. Haven’t been using Plantpress for very long but have on several occasions copied code into Notepad++ so I could collapse regions ( div, for loops) for better readability
One thing I often do is use external scripts instead of writing them inline. I can then use Visual Studio Code to edit them (it really is the best code editor out there… and it’s free!).
Using external scripts has the added benefits of not having to restart the service when you make changes to them, and in debug mode, it allows you to have the VS Code window side by side with Workflow, which makes it all easier.
