Puzzled as to why some files appear on the launcher and others do not. The “vector_clock_full.py” file is very useful but doesn’t appear. Works with Thonny but not otherwise. Simarly your touch example works with the launcher, but your Hello example does not.
As there’s quite a few Presto examples we only include a curated selection in the -with-filesystem builds. I think vector_clock_full.py is one of them though - it’s showing on the manifest here?
If you want to add more examples to the device you can save them to the root directory using Thonny, and they should automatically show up in the launcher.
