So, I started working on a copy of the geocaching map on Google Maps for personal usage, and copied the icons from the original map. To make it more clear, I added some custom icons, rapidly Photoshopped. One is for the caches I plan to hide ("blue star", as opposed to the owned caches' "yellow star"), and the other one is "!", for the mistery caches with corrected coordinates (but not yet logged).
The "!" icon.
Here you can see them on the customised map:

What I'm wondering is, can we please get an official icon (like the "!") to mark the solved misteries? It doesn't have to look like mine (that's just how I roll), but it could be really useful to distinguish these caches on the map.
