Hello guys, if like my previous post - there's new version of Grease Monkey script that contains also Google terrain map, Google hybrid map and standart Google map is set as default, so you don't have to change it in upper right corner. It also contains czech "Amapy.cz" but I guess you don't care... You can also disable/enable map in selection window.
