Tutorials for poe.trade, global 820 and loot filter

It is a well-known issue that Path of Exile is unfriendly to new players. One reason is that the game itself never introduce some very helpful third-party tools to players. For the first two years playing PoE, I didn't know that I can trade through poe.trade, or unlocking Uber lab with global 820 channel, or understanding how valuable an exalted orb is (I literally waste an exalted on a lv30 blade and feel happy about selling a tabula to vendor). I was playing in standard but is actually SSF.

I know these tools aren't made by GGG, but if everyone is using it, it will be unfair to hide it away from new players. I think GGG should officially introduce these tools to new players by adding tutorials about them inside the game, that will help new players a lot.

If it helps you feel better, a vendored tabula is going to be only 1-3 chaos away from that divine orb's price on the market. Spin one map and you've made up whatever deficit you think you vendored at.
