for a forum whose subject matter is so heavy based on code, the Insert Code function is pretty weak. a copy to clipboard button, a lift on character limits, or addition of file attachments would be VERY convenient! bandwidth is cheap! arduino files are small!
some sort of ranking system or users comments in the Playground would be nice! The playground looks like a very official establishment which leads one to believe that the code i contained within should work like the example sketches included with the ide. unfortunately, a lot of doesn't or needs a lot of tweaking and contains little to no comments. this can be very frustrating for a new user especially if the project contains additional or extensive hardware setups. user comments or a [ch10029][ch10029][ch10029][ch10025][ch10025] system could potentially save a ton of wasted hours and frustration.
my 2¢ fwiw. -sj
