I think that this simple idea would help us all with remembering where things are on the map.
Make a way for us to be able to make a mark in the map and maybe add some kind of message to it. Like if you wanted to remember where some collector is, or remember where the bosses spawn, all you would have to do is place the marker, add your own messsage, and wahla! Now it's at easy as looking on your map to find the thing that you marked. And the message will help YOU remember why you put the marker there.
