Hello, I have some ideas for Auctions. Here they are:
Being able to sort auctions by newest and time left (This may be a bad idea because people may spam-bid at the last second),
Instantly trade the items from the Create Auction page (like raffles) instead of the site inventory,
Auction Win and Outbid notifications at the top of the page (like when you won a raffle),
A notification at the top of the page (like when you won a raffle) telling the maker of the Auction that he needs to withdraw the items he got from the bidder of his Auction that ended,
Polls in Auctions (for example: What should I sell next? (Random answers here) or What do you think of auctions (Answers: Fantastic, Good, Meh, Bad, Terrible)),
Being able to see the items Original ID because with that you can see if the item is duped/clean or not,
and Auction Stats on profiles (like Auctions Entered, Auctions Created and Auctions Won).
These were my ideas for Auctions and I hope they will be added soon.
