Just out of curiosity, to get some insight and to spark a little discussion I thought I would bring this up in this section. What IDE or editor to you use to write your code? What features do you like and what are good plug-ins or enhancements? Features can be things like highlighting, code completion, versioning, etc. Many people use more than one as they don't all fit the bill for all types of coding environments and languages, so feel free to comment on what suits you the best in various scenarios ... and please state the type of languages you use with them.
