Google map integration is a great addition. 
Especially, if you have a large property. One addition that would be helpful is the ability to have more than one map. This would be especially helpful for large properties. What would be nice is a "master" Google earth map showing the entire property with select region hot buttons only. These buttons would then open up a zoomed in map of that region only. This way the main map would not be cluttered with all the icons overlapping upon one another. Only the region hot keys would show up on the master map. The zoomed in map could then show the zone icons for that particular area only. This is similar to what Hunter industry does (although they have limitless levels of zoomed maps for large commercial operations). They call this there IMMS (Irrigation Management & Monitoring Software). You may want to look into this. This and an upgraded metal or stainless steel controller to match a mainstream commercial grade controller (i.e. like the Hunter I-Core or ACC1200) would moved you into the big league.
