 There's an integration with External Item Description.
 It is also compatible with Mod Config Menu, if you want to toggle things (such as displaying info when on Curse Of The Blind)
 
-[strike]There's however a limitation: since (to my knowledge) there's no way to get information about seen items from the savefile, this mod takes it upon itself to track which item you picked up. (This means that when you install the mod for the first time, every item will be tagged as unseen)[/strike]

-EDIT: Turns out EID already has a support for this, using a save extractor, if you want to go down that route, here's the link to the extractor : https://github.com/wofsauge/External-Item-Descriptions/tree/master/scripts
-This mod is still somewhat relevant if you do not want to use external tools ^^

 Anyway, I hope that this mod will be useful to someone :)
