# Open Issues * Seeking by clicking on the seek bar sometimes doesn't work. It's something to do with the bidirectional mapping of the slider value to the solo tool property * If the recorder fails, it silently stops. There's no easy way to convey this to the nicegui because it's running in a separate thread. The solution is to make the `Recorder` API blocking instead, and call it from nicegui with `run.io_bound` * No test coverage for adhoc mode, recorder * `SessionManager` is getting a bit bloated (also handles recording uploads now)
