Google Keep may be better for this.
The Radio Paradise streaming app beta has just added a buffer configurable up to 8 hours for this purpose. It would be nice to see it in Xiia.
The search is still a little painful. If I filter something like 320kbps I have to go into each genre/subgenre to see the results. Quite time consuming. Could there be an 'All Genres' genre please?

Being able to bookmark directly from filter results would good, together with an indicator to see if a station has already been bookmarked.

Many thanks!
