Just to inform you that this function doesn't work properly.
I've UNchecked the flag under the options but all movies, after selecting a filter, are expanded after few milliseconds.
Filter... I mean right click on the list and select only.... view by year, by insert date.....
when I select a visual filter the list is expanded by default. I've checked and unchecked the flag "expand by default" under the options but nothing changes.
