Change size of waveform in Multitrack-Mode

In Multitrack, you can only do this by altering the clip gain - which would mean that you'd have to make a corresponding alteration in the other direction to the track gain. And of course that would affect the level of any clips you hadn't done this to, so it's not really ideal. In general I find it better to work like this, IOW get all the clips on a particular track so that their individual gains are reasonably equal; you get a clearer idea of what's going on in your track, and it can reduce the amount of automation adjustments you need to make.
