One thing I've noticed is that in Divine Divinity, containers said if they had anything in them or not with just a mouse-over, before you clicked on them. That saved a lot of time, and I kinda miss that quality-of-life feature in BG 3. I also remember that in Divine Divinity, you could rest to restore health and mana for free in a bed, but there was a hidden timer so you could only do it every so often, it wasn't unlimited.
