I may have a bit of a soft spot for English-y esolangs :) Yeah, LOLCODE should fit right in but Piet is tricky. I don't think a proper Piet editor can be added

I may have a bit of a soft spot for English-y esolangs :) Yeah, LOLCODE should fit right in but Piet is tricky. I don't think a proper Piet editor can be added, but a possibility is to map each color to a relevant character and set up the right background colors for Piet in the editor - let me know if that makes sense in usability. Some added functionality for exporting as PNG may be required too.
