With that check box ticked type the name of the blind your looking for or type in the holiday, i.e. Christmas in the search field. It should then display those blinds in that category. Hope this helps.
When you figure that out to see an actual list of Christmas skins let me know.
The only way to search for a skin is to use all or part of it's name. Example would be if you type in Christmas and any skins that have that in their name will show up. But that is all. another example. Take Karen's last year Christmas WB. If you type in Yule and hit search it will show but that is the only one visible. Has been this way for several years now. Now you can also search for an author but will only see their skins.
I think there is a lot involved to make it work correctly and don't see that happening as this has been brought up several times in the past. I really don't know how ID does this when making a specific list for a Holiday. Was hoping he did it this year so I could download and save a few of the older ones you don't get to see.
As far as searching for the name of one I can't even remember ones I made without looking in my folder for it. Well my memory is as short as. Will leave it there.
