I really love the philosophy of LightTable and will make a serious attempt with 0.5 to make it part of my standard dev workflow, but I keep wishing it had a single-stepping debugger built in, especially for clojure code. Am I doing something wrong that I keep depending on such an old-timey feature?

Again, thanks for the great work and sorry for talking about even more functionality (the existing LightTable is just so cool that I'd love to have it be even more awesome by including my favorite features :-)
