Format Bubble / No Marker

Hallo,
I 've installed your Comonent gmapfp with the plugins. At first I had the probleme, that I didn't make some IDs. The call of the plugin was written on the homepage, but nothing happend. Now everything works fine. I use my own kml-Files with defined markers. Now the plugin makes one more marker. Is it possible to make a place with an ID without setting a marker? At present my workaround is a 1x1 pixel image.
Is it possible to format the bubbles on the maps? I want to make some breaks in the lines of the bubbles. And is it possible to show the bubbles with a mouse over?

Here you can see it.

THANKS for that powerful Extension.
