This is probably a stupid question, but I cant seem to figure it out. When I set the flag to display unwatched, it works, but when I restart MP I have to set it again. How can I make the change permanent?
I don't think this is possible yet, but something like this will be implemented when filtering is further implemented.
I can only guess but probable some people would like to start with "added in the last x days/weeks" or so.
I didn't check for an existing issue though. so you might want to head over to Issues - moving-pictures - Google Code and check.
etheesdad you are wanting to start up with the watched movies filter turned on by default? I think that is not a problem. We can get that in for 0.7. Here is an issue on the tracker for the enhancement.
