Congratulations on Argo, its a great step forward and I am in the process of building my first model with it. I have not explored all the new features yet but have already found the Sketchup import really useful, got a mobile crane and a hula hoop already in this model :)
So, I brought this one up last year and Lars said it might be implemented in the future and a lot of others agreed that it would be great - nudge selected objects with cursor keys - I was SO hoping it would be in Argo - but not yet. Come on, we all want it!
How about releasing extra universes on a per universe basis? The price difference between Solo and Basic is really considerable, and I think if you sold extra universe for £300 or so then we could top up as and when the need arose.
