 ## To do
+- Make the CLI of handlers more useful
+- Make the `playerctl` handler independent of… playerctl. Use the [`mpris` crate](https://lib.rs/crates/mpris) directly instead.
+- Implement scrolling
 - Move loupedeck_serial and pa_volume_interface out of this repository.
 - Publish libraries to crates.io
 - Move handlers to their own repositories
