League Directory

Not sure if anything like this is implemented already but here's a suggestion for user education - With so many new leagues rewarding different categories of upgrades, I feel like it would be helpful to have a description of what a specific league rewards in the atlas map device. Back in 0.1, as a first time poe player I was massively confused by what each league icon meant at the time. Now with so much variation in league rewards I feel like having a central league directory from the map device becomes even more important. Perhaps there is a pop-out sidebar as a league directory which explains things like:

Breach: Specialize in Jewelry farming by finding breach-specific amulets, rings, and belts, as well as currency to improve the modifiers on jewelry.

Ritual: Specialize in Unique item farming and obtain omens to assist with crafting.

Vaal Temple: Specialize in Vaal currency to modify your gear beyond standard limits, making over-quality equipment, double-corrupt, and cultivate unique items to unlock vaal unique-variants found nowhere else.

and so on. This kind of stuff becomes intuitive over time for returning players, but still helpful for those returning from a break from the game or for new players.

On top of that, maybe there should be one central NPC who you can talk to in your hideout that is like an expanded verbal directory, who can talk to you about every league mechanic. I imagine Doryani is knowledgeable about what you may encounter in different leagues.
