I won't reply first question because I already replied it too many times I think...just do a quick search and you will find my answer to this at least 10 times on this forum.
About multi-vertices editing, I hope to bring that feature one day but 1-It's not that easy because many things have to be taken in account (number of selected vertices, what are their IDs, Multiple Highlight, Undo feature have to be rethink...) and 2-I'm currently working on TeamEditor so I'm not on 3DEditor for now.
Anyhow, I took all your reports, idea and questions for when I will come back to 3DEditor.
About Nurburgring, I heard about those troubles I hadn't work on Nurburgring at all, so I don't know what's wrong.
