A suggestion that comes from the likes of Risk of Rain 2, being able to see how the memories change and upgrade at each level. This would mean being able to view what their stats were at, say, '++'.

This particular suggestion came from Starfall *apparently* increasing the number of projectiles if you upgrade it enough, but it being unclear *when* that happens.

As to whether the essences follow the same linear upgrade path of '+' and so on, I'm not sure, as I'm very new to the game, but feel such a suggestion overall would be a nice overall addition to the collection menu.
