Thanks for the feedback! - On app links - these seem to work fine for me on iOS - are you on iOS or Android? Could you share an example link that didn't work? - On sats per minute - the minimum is currently 10 sats per minute but we will definitely consider lowering it if (when) the bitcoin price rises considerably - On playback speed granularity - it's on our roadmap to add more granular options - On Bluetooth headphone controls - what kind of customisation would you like?
