In fact, it works per tracks, according to time cursor position.
It works for multiple tracks if you try to choose to display the parent track of the track you want.
There is no overlapping in time item management for the moment, but sure. If two items overlaps, the second will be displayed only when the first will be finished.

(maybe you can start from the LUA version I send you by mail :P String operation will begin to be complicated
