Yes, I’m disappointed by the lack of responsiveness. That’s why I forked the project, reluctantly.
One way or another the project has a future. I’m an experienced software developer (retired from Microsoft) and am quite capable and have the time to provide regular releases on all three platforms, providing support, etc.
I set out six months ago to develop from scratch an open source tool based on the concepts of Geomaestro – http://www.zogotounga.net/GM/eGM0.html , then found the open source project IanniX and offered to work with them, but unfortunately they seem too busy to be responsive. I can carry on independently if necessary.
