The "book container" is an excellent and logical place to put my spell scrolls (and various notes and letters). But sadly, my wizard character cannot learn spells from the scrolls that are stored inside containers. This seems like a bug that upcoming patches may be able to fix, since all other items (alchemy items, camp supplies, etc.) inside containers can still be used.
"Items inside containers don't seem to count as items inside your inventory" is an issue that was pointed multiple times across the EA and the only logical conclusion is that Larian didn't think it was important enough to fix back then.
More in general, I'm finding myself once again in the position to stress that while "better container management" would SOMEWHAT help to alleviate the issues of the current inventory management, I still don't think it would be anywhere near enough to make it good. Especially when it would need to through the whole "you'll need to manually flag containers to set them for different item types".
So my (weak) hope is that we'll get far more meaningful improvements over time.
My ideal baseline would start with an unified inventory for each player (and then include additional improvements like better sorting options) rather than having separate inventories for each characters... which doesn't even seem to serve any gameplay purpose aside from making moving items around an annoyance (given that everyone can access anyone's bags even in combat with no restriction whatsoever).
