I agree on the part, that NPCs drop to much "stuff". Its exhausting to carry that shit around.
I´d be glad for an inventory with more features, such as: groupy all non-magical weapons and put them in a box or sth like that. Or the NPCs just drop less weapons and stuff. honestly, it gets sold anyways. just cut the ability to pick up each and every goblin bow and give the leaders some cash as loot.
Regarding magical items:
I felt there were way to many. In DnD5e magical weapons are rare and pricy. something you will not find by a little merchant that hangs around in a small refugee camp. I have no issues only having a few magical wepaons for the entire group at level 4. But in fact i had like 5 magical weapons for each character to pick form. only magical light weapons were an issue, but i had tons of magical two handed options. like 5 spears/staffs, greatswords, axes, clubs etc. Was way too much for my taste.
