This was probably suggested before.
Something like this: 11/XX.
It would be nice to have this to lore notes too. It would be awesome if we actually knew how many lore we were missing.
This could be considered mental and emotional abuse against OCD players given how difficult it is to actually acquire all blueprints.
I know you can check how many lore notes a char has here https://www.grimtools.com/checklist/shrines/normal
Perhaps Dammit will add #blueprints too where one uploads the “forumlas” file
Here is the list of all blueprints https://www.grimtools.com/db/category/blueprints/items
wondering if anyone would be interested in knowing how many bp’s are left considering there are so many “junk” items like level 68-75 Mythical set helms etc…
One could take this step even further, why not implement a counter for the entire item database for Epics and Legendaries too? 
Yeah, I know of this, but it would be nice to have it in-game. So we wouldn’t need to come here and search one by one.
Same goes here. A search bar for the blueprints you own would be nice too.
