VSE CHANNEL GROUPS

I use metastrips when I want strips to behave as one single strips, but sometimes only connecting them with the chain icon is better because I need to see them separetely while cutting the video. That's why I think it would be of great benefit to have channels that we could group just for the sake of organization, so we can colapse a group of them and open when we need to edit them. It would not change the order of channels, so it wouldn't be possible (in my idea) to have channel 7 grouped with channel 2 for instance, or to have channels inside channels, i think that would break the code, and for that metastrips are useful, but just for colapsing and organizing really. Also, it would be nice to have them be resizeble, like, make a strip taller than others, like most DAWs software have. So a arrow cursor could appear in between channels for us to resize them, make some very thin, and others, for instance, the video strip, taller for us to see the thumbnail.
