Tap Forms scripting

I’m looking into upgrading to Tap Forms 5 mainly because my current version doesn’t allow linking pre-existing records.
I’m intrigued by the scripting capabilities and I’ve created one script in the demo to show all the nested relationships, which is pretty neat.

Does anyone here have any experience with Tap Forms 5? I’m hesitating because it is quite a bit of money to upgrade on macOS and iOS, so I’d appreciate any reviews you could offer, or cool examples of its power.
