Good, but a few annoying bugs

I have used this app in the past. I like the new UI a lot better, but I have trouble with the app crashing when trying to edit the plain text. I used to use this app alot when debugging jSON from a website so I could see the relationships more clearly. I wasn't able to do basic editing like select-all or pasting without it crashing. I had to paste it into a new file adn save as a jSON file on the desktop in order to inspect the contents. I know a recent update can be hard to iron out edge cases like mine probably is, so I'm hopeful for a more stable release soon.

Good JSON Viewer

The UI could use some improvement.

Expectations: (a) Clicking on a table row should show me its contents; instead, a double-click is required. (b) instead of using a simple table, a table using drop-triangles is more readily understood; (c) using multiple windows instead of multiple tabs makes the different files easier to find.

I want to love it, but it crashes.

I love Jayson on iOS. Unfortunately, this Catalyst version just doesn't perform like the iOS version does. It crashes whenever I navigate too much through a complex JSON, which is exactly why I need Jayson in the first place. It's a hindrance to my workflow. If it didn't crash so much, I'd give it five stars. I had high hopes for this app on macOS, but it can't last through normal sessions of usage without crashing time after time. I'm disappointed to say the least.
