I want to make a suggestion to two other components of the Arduino "conglomerate"
1) I would like to see a better outfit or design / layout for arduino.cc. This grey theme is antiseptic and doesn't show the design roots of Arduino nor that it is a system for artists, designers and other ordinary humans. Sites like makezine.com or instructables are much more appealing.
2) It's a horror to edit in playground. There I would like to seee more contemporay editing features.
