I am one of those people who you are making this tool for! I work within Hotel and Exhibition spaces all the time, and since they usually start as big rectangles, there's no holes bared for what people do within those spaces!
Having to layout a couple thousand seats is usual for me, and I would imagine anyone working in Vegas, Orlando, Chicago... and that's just i the USA.
I'm glad to hear this tool is being improved, and I also appreciate the info from behind the scenes of your algorithms.
Thank you for your work!!
