The Dark Brotherhood string of quests keep repeating the same few kill assignments over and over.
Also the quest to give the guy a dragon bone and dragon scale along with the "bring a new recruit" quests were both done. They both indicated complete, but still show up in the quest list as needing to be done. When I go back and talk with them (I think his name is Eserben or something like that) there is no option to continue.

Esbern's quest is bugged, it won't complete.

The other quests are "radiant quests" which means they'll continue forever.

Some do that. Most are repeatable though. I've fetched refined frost salts for that guy in Dawnstar more than once.

A few cause problems. Like if you read that book Legend of the Red Eagle it starts the Red Eagle sword quest. If you complete that quest and accidentally read the book again it starts the quest a second time but it can never be completed twice because the sword and boss are unique.
I also had a problem with a Riften jarl quest which asks you to kill a specific orc bandit but that bandit only appears once, but the quest can repeat meaning it gets stuck.

I see, I would call that a "bug". But I'll try to simply ignore their presence in my quest list.
Thank you for you replies.

Add this to the reasons why I would like the ability to delete undesired quests from my list.

Same as killing the spiders in Red Belly Mine, I did that one a few times over just to get more ebony ore. I think that is what started boring me in Skyrim. I could finish one quest and a day or two later someone wants me to go back to the same place to do another quest. Overboard randonized quests IMO.
