The persuasion wheel was awful, more often than not I just bribed my way up as I couldnt be arsed mucking around with it.
I put items quite frequently in my display cases... it just took a lot of effort dropping the item then picking it up in front of you and trying to rotate it through nudging off the edges of the case to get it sitting just right. Full agreement that they could make it a little easier though, like instead of having to use the floaty "hold" key make it so you just pinpoint the area you want to place the item and say "Place here".
Voice actors.. yeah, more would be nice.
Silt striders? No thanks. They were cool and they fitted nicely into Morrowind but I always saw them as like a backwards means of transport, replaced in Oblivion by horses. Pretty sure a silt strider's legs would freeze off in Skyrim too.

When I first started playing I didnt actually know about the fast-travel and I enjoyed exploring the land but even when I discovered the fast-track function I rarely used it. I wouldnt like to see it removed though because theres times when you just cant be arsed traveling. For example when you're about to finish playing but you want to quickly get back to a city before saving and closing.
For me the minor thing to change would be to allow key NPCs to be killed. I appreciate this can mess up a storyline but I recall a game that allowed you to kill key people quite happily. The catch was as soon as they were killed you got a message saying, "This world is now doomed due to death" or similar but you could carry on playing if you wanted or revert to the last save game.
Theres been times after Ive completed all the quests Ive wanted to do and just wanted to wipe certain people out and steal their castles for example but they just keep falling unconsious instead of dying.
