Hi Everyone,
Having recently got a Yoto player for our child and created some of our own cards/playlists it quickly became apparent that this can be a rather tedious process.
To this end I've create Yoto-UP. This is a set of (open source) python scripts / tools / GUI to make card management easier.
Whilst it originally started it as a command line based tool (with a rich TUI interface), it has since grown to encompass a fully featured GUI (got to keep the wife happy...).
It is designed to allow quick card creation from a folder / list of files but also has a number of other time saving features such as
automatic icon selection and upload (with icon searching for when it fails to select an appropriate title)
cover art search (with automatic upload)
playlist management including, track reordering, automatic overlay / key setting
many other useful (or not so useful) features
It is still in its infancy so will have bugs, but it has reached a stage where it may well be useful to people.
