[Idea] In-game book shelf
Books are a bit of a problem right now, there's so many of them taking up space, and if you wish to keep them it means a lot of scrolling for other items in that tab. My suggestion is to add an in-game book shelf of sorts, it could be a simple UI where every book in the game is shown, greyed out until you've looted one, the first one you loot, or "first edition" cannot be sold, and will always stay in this UI, you could perhaps give a reward for completing the whole collection. And whenever a merchant is selling a book, or you find one out and about it should say if you already have it in your collection so you can quickly discard duplicates.
That or take the easy way out and give books their own tab.
