Can I rename or delete a project, or change which project a conversation is in?

Yes, you can rename or delete any project or conversation. To access this feature, just swipe left on the conversation or project like you would do in the iMessage or Mail app.

You cannot move conversations to different projects yet but we hope to add it in the future. If you really want to do this, you could export the audio recording outside Cassette and then import it back into Cassette. That way, you'll be able to add it to a different project and delete it from your existing project. However, keep in mind that you will lose your transcription and bookmarks this way so make sure to back them up.
