Hi Bill,
The mouseover map is a neat feature, I will see about adding it, the biggest key will be to make sure it does not take a lot of resources to make it happen. Also I like the trend idea, I think I can do this, but the way I do it may cause problems with certain gauges.
When I get a new version around I will make an option to use either kcfs or cfs, for other users who may want it.
I will see about pulling the Lake Erie data no guarantees but I will try.
