Mixxx should allow to toggle between beat-grid and raw beats once the song is already analyzed without the need of re-analyze the song.

When dealing with songs with a loose tempo, I have to comment the songs I need to re-analyze, and then go to the analyze view to redo the job. Just checking / unchecking a check-box on the track's properties dialog seems much more practical to me.
