@zabaznov-roman Thanks, I appreciate the PR and I'll give this a test first & then do some reviews :-)

Also in future its good if you have a screenshot or video that helps to quickly see how it works before running it.

Hi @zabaznov-roman While testing, I found some issues.

1. Audio seek affects all recordings, not just the one being seeked

Root cause: Single shared audio player state for multiple recordings. AudioPlayerViewModel uses one _uiState to manage playback for all recordings, so seeking any single audio updates the shared state and ends up seeking every audio instance at once.

2. Delete icon overlaps the audio duration text & slide to delete affected

Root cause: RecordingItem uses a Box layout with the delete button aligned to TopEnd, which causes it to overlap the duration text instead of being positioned separately.

3. Transcription always transcribes the first audio

Root cause: When navigating to the transcription screen, the code always references the legacy recording.recordingPath instead of asking which one it is to transcribe.
