ComboBox should not collect play history

Description
randomly doubble clicking on once clips in Sources they are played back
and the ComboBox shows the name of the clip.
clicking on the combobox after doing that for some time, one is presented
with some sort of history of the files played.
if this combobox exists, it should not list clips more than once.
and not only after they are played, but once they are added.
with many sources this list will get rather long, i dont think it scales well.
