Thank you! You completely got it. That's exactly what I've been trying to say. Obviously we've lives to live, work to do, etc - you may abandon the game for several weeks, then come back to it. You're playing for fun - the challenge of finding the quest locations etc is part of the enjoyment, but once you've found them, they should be marked on the map automatically, so that when you come back to it later, you're not lost as to what you've already won, and what you've yet to win.
Summary being:
1) give us 'quest giver locations' on the map - I've activated a side quest, talked to some guy, he's now highlighted on the map
2) I've found an important location relevant to the quest, it's been revealed to me that it's relevant to the quest, so instead of me having to manually mark it, the game does it for me
3) Where I should be going to complete the quest should never be marked initially on the map - it's only marked when I've found it
