I hope to read the original configuration.

This project is very well done, though it would be perfect if it could read and write the original Launchpad configuration.
“Launchpad Manager” can read and write the original Launchpad configuration, so I hope you can take a look at it for reference.

Hey, I don't think this Launchpad Manager app will be supported long enough after the Tahoe release, so I don't know If the game is worth the candle to support their format. If you familiar with their format and it's a readable file (not binary), you can convert it using AI to json config of this app, which can be found here: /Users/{your username}/Library/Application Support/BetterLaunchpad/config.json
