Can someone tell me where the third party add ons come from?I'm asking because i'm wondering if there's one that will display a file i've already downloaded in a particular color when browsing someone's library so I don't download the same file again.If there isn't one, where can I get in contact with someone who can create one?I don't know the first thing about programming, so it's not something I can do myself, but this is an issue I bump up against a lot as I have a pretty extensive library and sometimes the same file will circulate under different files names.Any help would be appreciated.
