As part of the group that includes xvideos, I expected the same functionality, but in fact there are multiple design and technical problems with this website. For one, the thumbnails are too small. Two, even when I create favourites folders, I cannot add to those folders. I can with some difficulty create folders, but it is impossible to add new videos to them.
I've also noticed the Favorites fuction only seems to work with some videos. The little Favorites heart will turn red, indicating I've Favorited a certain video, yet when I check for it in my Favorites folder it's not there. It's pathetic when a porn site isn't completely capable of allowing users to do one of the most basic functions.
