I just saw a little webcast on code bubbles. Someone is writing this up as a plugin to Eclipse. It is generating a lot of excitement and looks really efficient way of coding. Listing here so that JetBrains can consider this new pardaigm as a possible redesign of future IDEA implementations if they haven't already. The idea isn't new. Scala has had this a while but its very exciting. I would love my favorite IDE (IDEA) to have this in its future plans.
