it seems there is no way to "lock" a track to prevent further editing, is this correct?
On a similar note, there doesn't seem to be a way to select all the events in a single track (e.g. if i want to slip them all by a couple of frames)
You can also use AUto-Ripple function, set to Affected Track and when you slip the first of all the clips on a selected track, all the rest of the events on the track will follow.
