Solo Button for Tracks (audio and video)

I’d like to suggest a “solo button” for all tracks / channels, as well as for the filter section. Such a solo button allows you to quickly monitor a signal all by itself, or with a group of other solo enabled channels, without needing to mute all of the channels manually that you don’t want to view/listen. It is known in all audio mixers. Especially in very complex mixes it will speed up the work significantly and you can e.g. improve the filter settings in a single track and then turn back to the whole mix. The efford to implement is low. If useful, it could be combined also with a PFL option (on the same button) that would deactivate with a single click all filters on the track (to monitor the original look and to speed up the playback).
