Back in the day I used CrimsonEditor alot, it was a good, free source code editor. Unfortunately it was a one man job and the developer stopped maintaining the application in late 2004. Enter the EmeraldEditor group! EmeraldEditor intends to be a new CrimsonEditor-like editor (ugh that's an awkward scentence), written to be cross-platform and open source. But the news gets better, CrimsonEditor itself was open sourced by it's author and the EE team has effectively taken over maintenance of it! So grab the code and get cracking! I'm glad to have CrimsonEditor back and look forward to EmeraldEditor.
