For Track, select All or one of the tracks the listed values in the result.

Now, widgets for Clips and for Collections can also be filtered by track.

For TouchTest users, by-track filters can also be used as an equivalent of by-device filtering when there is one device per track (e.g. by selecting a device in the Track's Location drop-down). It should be noted that if devices are set at the clip-level, then using the track filter as an equivalent of "location" will not be possible.
