One of most irritating issues to me in this game is the following distance of followers and mounts. It piss me off when my mout come too close of me blocking my way or pinning me in the corner or ground. Sometimes my mount have even pinned me in the ground/wall and I had to suicide to escape.
Please look to a old game called Neverwinter Nights and look how you can control the distance the follower can keep behind you.
Please add this option to follower painel: Follow Distance - Near, Medium, Far.
