thank you for the reply. In the meantime I have implemented the editor and it is now available for the group.
vz.cain-project.com/VZEdit.html
I tried to post that already 5 days ago, but it seems like I was doing something wrong.
It is browser based and should be applicable for Win and Mac, given the jazz plug in is installed and activated.
I do not track or store any of the data, which is being edited with the tool. Also I am happy to receive feedback on how to improve the editor.
Cheers,
Pete
