Inconsistent stopping of the playhead between preview and recording.
This is only a tiny issue, but an issue non the less.
When playing back on the timeline, Kdenlive automatically stops ON the last frame, not AFTER the last frame. If you want to record audio on that same track, you have to advance one frame.
When recording and stopping, Kdenlive automatically stops AFTER the last frame, allowing you to just hit record again and carrying on recording.
So, when recording, it might be a good idea to check if the next frame is empty, and continue recording from there, or have kdenlive stop playback on the first empty frame with no more frames to follow, rather than stopping ON the last frame of the project.
