With all the overlap of content from so many VR sites, it's hard to keep up with what you download or have seen on other VR sites.
What would be really nice is if you somehow could import your favorites in from certain other sites and it updated the similar videos here and marked them as a favorite with the heart icon. It would be nice if you could work with other VR websites to get them to partner and make this a VR industry thing of having the ability to export/import favorites to other sites.
The benefit to the sites are more videos get favorites and the numbers go up and it really showcases how popular some videos are. The benefit to the sites are it also will reduce the amount of wasted bandwidth on streaming or downloading things that people already have downloaded and later have to delete or skip past. The benefit to the users are it makes signing up on a site more convenient to access that sites exclusive content that they haven't seen yet or downloaded yet.
I know getting something like this implemented might be a challenge, but if you could just get a deal worked out between you and POVR, that would be really great where you both allowed one another to export/import favorites for those who possibly have accounts at both or who switch back and forth on sign ups, as new exclusives are released.
Then you could have an option to enable the hiding of favorites from the catalogue so people can just view what they have not favorited, seen or downloaded so far.
