I was playing through the DLC and found the most annoying minimap icon: a blinking alert completely unrelated to what I am currently doing. After a quick google I found out if I complete the quest the same blinking icon will start to appear all over the game with no in-game option to disable it. To my surprise, it doesn't seem to be a mod for that either. A few "better minimap" mods, but none that let you customize what icons appear, as far I can tell.
So that is my pitch: a mod that allow you to pick and choose which icons appear in your minimap. Personally I only care about removing the annoying blinking steering wheel, but I figure a more complete mod with more customizable options would be cool.
