This thread has been silent for a little while, so I thought that
I would slip in.

I have some ideas for a "horizontal piano roll"-like widget with
the capability of multiple tracks and a time scale.
Individual tracks would be child widgets - for example "waveform"
displays.
The widget would also be able to handle scrolling/page-flipping
the tracks during playback and to help child widgets with
preview-buffering.

I just want to know if there is any demand for such a widget.
I don't have any need for it myself, but I think it would be fun
to make one. I can write it either for GTK or Qt.
