If you want to build your custom version of Moodle Desktop, please follow the Electron Guides that you will find in https://electron.atom.io/docs/
Please, consider the following:
- For building a Windows version you will need a Windows computer.
- The Mac version will require a Mac computer.
- The Linux version may require a Linux distribution (depending on the selected target).
Note also that if you want to publish your custom versions in the Windows or Apple stores, you will need to sign-up for a developer account (it costs money).
Moodle HQ provides a branding service of Moodle Desktop via the The Branded Moodle Mobile App. This service includes publishing in the stores and code signing.
Deleting the profile
Sometimes the app can get into a bad state and you might want to delete its data. When using the desktop environment, you need to delete the contents of the profile folder.
- On Windows this can sometimes be found at C:\Users\ (your username) \AppData\Roaming\moodlemobile
Just quit the app, delete all the files in this folder, and open it again; you'll start with a fresh app.
