After upgrading to Ubuntu 16.04 I noticed that Totem (the default video player) is no longer portraying its sidebar, which includes the much useful stack playlist. I judged this to be a bug, but it turns out this was a conscientious regression introduced by the software developers.
Therefore I am looking for an easy way to get back to an earlier Totem release. This could either be with a fork, say, a Nemo counterpart to Totem, or through an earlier full featured release (which I believe to have been 3.12) available from a PPA.
