I agree with you. I would like to have this features in WED but unfortunately it is not the case. Rhuarc does a good job to close this gap.
And concerning you question: Yes, I sometimes earn a bit money with my modelling. But that is not the point. I will spend money for this hobby and I can calculate quite well. I can go to work for 2 hours more to earn the needed money for a plugin or I can spend much more hours to achieve that myself. What option is better? Since I do not want to become I shader profi and I like to create complete worlds with models and levels I would say I save my precious time.
