Yes, App ac51319449 is open source, so anybody can adjust anything.
There is a link to the source code under the ‘Sources’ heading in the catalog entry.
What do you think about adapt this line for your scenario?
When you have made a change, you can run your app using the path to the directory containing the program code files. That works both for URLs into a git repository and also paths in your local file system.
If you want only to replace the text to identify the menu entry, it is probably easier to edit the file directly on GitHub.
The most common way I see to turn off a module is to use a command to toggle the module. A toggle command will turn it on if it was off and will turn it off if it was on.
To get a function that only turns a module off, you can combine the toggling effect with a branch on whether that module is currently on.
What do you think of this approach? Does that work for you?
