Hey developer! I had primarily gotten interested in this app because it supports and can edit JSON files. This app allows me to view JSON files that one of my counter apps use to make backups of my counter data. I can edit counter data within the JSON backup if need be with this app. But not only that it also supports other formats: markdown, .txt, Swift, Python, C++, LUA, and so on. It does what I need and so much more. I have already paid for premium features, so I’m happy to support you for the hard work you have put into this app. It’s on my phone to stay. Thank you, Runestone! 💗Thank you!💗 Hey developer! I had primarily gotten interested in this app because it supports and can edit JSON files.

Excellent ! Pasting can be tricky. A ‘recent’ submenu would be exquisite… Nice & easy Excellent ! Pasting can be tricky. A ‘recent’ submenu would be exquisite…
All I needed was a plain text editor. I have thousands of files from when I was writing songs regularly and keeping other types of notes in plain text inside a UNIX environment. I don’t live in that environment anymore, but I still have all of these plain text files that I need to maintain in periodically update. Long comes your app!
