If You Are a Trader Check This Out

so no trader here. ok.

that feature is not really necessary

That would be useless IMHO.
Instead, they should stop making dota2 items and sets so dota2 key price would back to their old price.

Pop ups are super annoying unless you are getting a free game. Try getting 10 trade offers at once.

We already get a green icon. I don't need a popup disruption. If you're a trader, you're looking at these notifications from time to time anyway.
