Thanks balloni,
shared "as text" was based on sharing certain location (point), but elevation and accuracy was always from GPS, stupid. So elevation will be now correctly for shared coordinates. I've removed "accuracy" value because we share map center, not GPS location. I also believe it's used really rarely and also "accuracy value" can't be much trusted.
"Share as KML" ... fixed by enabling compression to KMZ, which include attachments. And missing info about geocache ... well, you probably know, but KML files do not have support for geocaches, so it is not simply! possible to add all geocaching data into KML file, thanks for understanding.
