I have watched talented Sketchup users do amazing things. However, I still find that there are no low cost, ideal apps for designing floor plans quickly and easily. I'm a big fan of open source (I write it, too), and would love to see this product mature into the best software available; it has started out on the right foot. However, users make the best product testers, and it is important to listen. Often they'll come up with the ideas that make a piece of software go from good to great. Hopefully, someone will hear our pleas. If time permits, maybe I'll find a chance to donate the code to do this...
