Thank you for the input. Hopefully we keep seeing your new creations. I always get excited to see people coming in that are level designers at heart. The masses use WW for just the models, but I'm eager to see more people getting into the level design tools. (I first started WW when I had been mostly building levels in Hammer and was mortified that making props was so complicated. Now I make levels in Max alone.)
Continue to share your feedback (and more screen shots). There are several guys on here who can help solve problems whenever they arise.
As far as expanding to other engines. It's certainly something that has crossed my mind. But I think that the incentive for me is too low. While many people use WW for models, the people interested in the level design side are very few. I have played around in EU4, so if I ever start some major project in that engine I am sure to adapt WW for that. But at this point, my focus is on CS:GO/Insurgency so I cannot currently justify the effort.
