1: Non buggy Racial ability bonuses from PHB.
2: Deities for Paladins (again non buggy)
The two above should have been default in game.
3: I would also love a mod that makes it possible to walk around with 5 companions (with full reactivity from all of them), But whenever Combat starts you only fight with party of 4 (2 others are frozen out, cant act and cant be targeted).
4: Boots as clothing
5: Mod that makes it possible to change The look of armour (to something else in inventory for example).
