Increase maximum zoom in?

[Wikfizbik]

Is there a way to increase the maximum zoom in level?

Ocasionaly, a lot of similar POI get clumped together, and it would be nice to be able to zoom in further to make it easier to mouseover them. As it is now, when this happens, I basically turn off all poi, then turn them on one layer at a time until I find what I'm looking for (it usually works, but being able to just zoom in until they are spaced apart enough would be great).

My UI editing skills are poor, but if this is possible and someone can point me to what to look for, I can at least give a try at gettign it to do what I want.

Thanks,
