First and most important..

- Disabling fast traveling to every location you discovered. Only from major cities you can fast travel to major cities only. The rest go by horse.

- Horse can now move backwards, like real life! if you press S he will start to move backwards.

- More options for AI. For examble, frost trolls grabbing a tree to get a more range attack if you hide in a rock.

- 1 or 2 more lockpicking minigames.

- Steal will be a minigame too, like lockpicking, you will have a dark bag and you mouse pointer will be a hand, when your character feels somthing you can grab it without knowing waht it is. Unless you upgrade your skills on steal.

- Better visual for marketin, enchanting and all that is reffered to item management.

- Golden Chest, this golden chest will have a limited amount of slots but will be shared all over your houses. Normal chests will be there too but they will have tabs like your character have.

- Cloth Smithing for mages.

- Levitation for Ilusionist only.

- Merchant Routes, this will allow you to sent a squire with the items you want to the major cities markets. Squires will have their own level, and they can die. ( since fast traveling will not work to any location you will spend a lot of time riding, this will allow you to make money while questing ).

- All enemy cats now go stealth and they are not show in your compass.

- 6 limbs dragons this will allow the dragons to charge and be more deadly on the ground.

and those are the mods i want to have in the future.
This is my entirely personal opinion.

PS I will be working in some of these myself.
