I would kindly suggest that the companions that are following you move out of your way as soon as you get very close to them. They frequently block me in entrances, especially the horse. It can be touching distance as you still need to mount, or maybe if you move towards them for 2 seconds, something like that. As it stands you have to cheat your way out by moving at the opposite end of a room for instance so they’d either follow you inside, unblocking the door, or they spawn outside of the walls of the room you just moved across. Either way, it’s super cumbersome and takes away from the game experience.
