Selecting Items in raffles and trades is honestly a hassle, one moment you found what you want to select and with one roll of the middle mouse button, It's gone. It's slightly inconvenient and has stopped me from using the raffle and trading features at some points when I've just had enough of continuous searching. It's much easier on mobile.

I think adding a search feature to these lists would allow the process to be much simpler.

Though I'm not sure if anyone else has this issue. ^^;
