After I uploaded a short Tutorial on one way of getting all the tracks on the timeline back to the same size there was a small discussion about the topic.
The method I had suggested had the side effect of resetting all the defaults for the tracks.
Not such a good idea if you had given different clips their own specific colours etc.
One of the more experienced MC users suggested the "View Menu" as a better alternative.
However even the View Menu has a drawback in getting all tracks back to the same size.

The suggestion did, however, get me interested in using the View Menu more often.
The Tutorial describes one way of using it, as well as pointing out the drawback in using it to get all tracks back to the same height.
