For me it’s more about understanding what’s going on inside the tablet. The only real “change” I’ve made in the software was renaming the “Life/oragnize” template category to “LifeOrg” in order to make room on the screen for a new “Custom” category, which I use for the custom templates I use - and that was done by editing a JSON file, not by monkey-patching the xochitl executable itself (which makes me nervous).

Other than that, everything I’ve done is writing programs to interact with the tablet (backups, list files, delete files which aren’t cleaned up on tablets that don’t connect to a cloud account, etc.), and writing documentation about what I’m learning along the way.
