Hey Wesley,
We plan to improve the custom tiles a little, but I don't plan to do what you suggest. We always show 20markers and as many tiles as possible. I can for example hide the markers when you zoomed out, but I find that this is an unnecessary complication. Also I can remove the dot under the marker, but this would make the code more complicated and I don't see any benefit in not having the dot anyway... you can't click it, you can click on the marker and it is always clear that you have to click on the marker and not on the dot, or am I mistaken?
Regards,
Daniel
