1. Jump shortcut: this is the most commonly used skill out of combat (maybe also in combat too) and would be nice to have it on a shortcut
2. Camera level scrolling: the best example in the goblin camp or even in the githyanki fight when the enemy climb up really high and you have to try to climb with the camera to see the enemy, so that would be nice to have something like Shift + Mouse wheel
3. Shared health potion/food pool: you can put a bag on the hotbar and you can even use a consumable from a different character's inventory, but you have to open the inventory or change to that character who have the backpack on the hotbar. There could be a sub-inventory where you could put items there like food, potion, scrolls etc. there could be an option like the move to valuables in the inventory and you could also pick up items directly into that section
4. Faster combat: probably there are a couple topic specially for this, but more specifically the stuck enemies whos just wait in their position
5. Enemy action and bonus action in examine: with the higher lvl enemies it feel like they attack significantly more than the player character could
