You can do this, at least on the PC. Hold down the 'F' key and rotate the camera to your heart's content.
It's kinda dodgy, but it works... sorta.

Harvest frost miriam, elven ears and garlic outdoors (wilderness or farms).
Talk to guards.
Wear two rings.
Use grainmills for something useful, like grinding mammoth tusks into powder.

Actually, my char alwayd wanted to become a baker...
But he failed in backing bread, so he became an Adventurer.

hold a shield and use magic in the other hand. you can do this, kind of, but you have to use the favorites menu to swap spells instead of using the hotkeys. i feel like this could be a very easy fix that essentially adds a class to the game.

I thought mudcrabs would be the ultimate weak enemy that you could kill in 1 shot like on oblivion, they are a bit more sturdy in this game , have killed me more than once and gotten me to low health more than I would like to admit at lower levels. I like that there are different sizes of them too ... dont see that in any other enemy type as far as I recall.

Most of those things all of you point, were just solved by mods so, I missed them first, now they′re covered.
The only thing I really want, is Horse Combat. Nothing more.

heres what i was expecting...

-being able to effect the economy...
-we got told if you burn a mill down that area would stop selling arrows ect....
-the way they described the smithing skill and all the different armors sounded like we would be able to customise it to an extent...
-fishing
-farming ( i know you can pick some wheat and sell it, but come on i was expectin to run a proper farm or something).

Since i'm a mighty dragonborne i thought i could FUS RO DAH an avalanche

Pulling a cart, an related to that, make a dog pull a cart. The disappointment when I discovered you could only massively hurt yourself with them like in Jack*ss...

Spontaneously start a brawl. Unfortunately, the other party always pulls out his weapon instead of his fists, and YOU get the bounty! Oblivion was better in that regard, and I mean before they patched the bug wherein you would swing your fists a bit in a big group of npc's and they'd start fighting each other.

Simon Game says: No fishing/navigating a boat/do anything besides swimming, looting or drowning underwater/killing yourself on the mill saw allowed!

You can only get pelts or meat from hunted killed animals ...? No skull, bones or organs (or very few)?

Apparently, it's too much asked of your character to both jump and shout. The amount of times I died when trying to use Ethereal ... And so, we'll never be able to act like Tarzan and let out a deep manly cry when jumping down from a high ledge (yeah yeah, Tarzan doesn't do that, but we need to get creative when we can't swing you know?) Also, same applies for riding a horse and shouting.

Forsworn being ungrateful bastards. You help their leader, but apparently they don't really care about that. Keep on attacking the one who might be on our side! Even if (s)he wears the same uniform as you.

Immortal children. I wonder why they even stay with their parents, if they can't die anyway. It's not like they're really essential in the game. And let's face it, kids can die as easily as advlts. Besides, I find it really ironic how the parents can die while the child has to live on. Have a great life on your own, kid, maybe you'll even be sent to that fabulous orphanage in Riften! Can't have enough trauma after all, huh.

Ask npc's from a town where another npc from that town is roaming about. i don't know, I think it's kinda weird how you have to either know the whole day schedule from that particular npc like a true stalker, or simply accidentally stumble on them (well, I play without the quest markers).
Somewhat related to that: being completely dependent on quest markers to do the quests. Really Bethesda ... If it gets any worse than this in the next game, I give up on you. I hate not having to think at all while playing a game, makes me completely forget what I've been doing and ruins the gaming experience to me. Then I guess I better play no game at all and waste my time on something a little more productive.

Have shouting contests with dragons. I mean, I'm the Dragonborn, so why can't I decently fight dragons on their own turf?
Kinda related: why does Kyne's Peace trip a tripwire?! I had to run for my life when I only wanted to calm down some minor rats ...

Idem!
