Acknowledgements

• Thanks to Marijn Haverbeke for developing ProseMirror!
• Thanks to Hendrik Erz for keeping Zettlr open source! When I started developing Noteworthy, I had no clue how to set up an Electron app or responsibly interact with the user’s file system from Node, and the Zettlr source was a great reference.
• Thanks to Microsoft for keeping VS Code open source! I learned a lot by reading the source of the VS Code tree viewer and plugin system.
• Thanks to Fabio Spampinato for releasing the source to an early version Notable!
