Not a coder, but I can create a custom button on the Presto, but what is the right code for launching another .py file that is stored on the Presto? Thank you. Just trying to make a simple dashboard to launch a few apps.

I did mine by adapting the code from the example launcher app that came with the Presto. Works by writing the app name into a text file on ramfs.

You can see the code in GitHub too:
