I’m back with another great addition to this wish list :0)
I was wondering if it would be possible to use animated .gif files for custom icons. I actually uploaded one but there is no animation. I googled around and found some info about ‘optimized: false’, un-optimizing icons for animation via http://stackoverflow.com/questions/5979676/gif-marker-google-maps . Not sure if this is a good idea for the rest of the icons but if there was a checkbox for it that would be waayy kewl!
