Anyone alter/edit Zumo dashboards?

[Emoto]

It seems that the dashboards in Zumos are defined in a dashboard folder and are files with names like GarminNavigon_480x272.dshb. One can open them with notepad and see that the legible sections are perhaps XML.

Any of you guys experimented with editing one of these puppies (after backing up, of course!)?

Seems like one could make the fields smaller or make them go away or whatever, or add another choice.
