At first: thank you for this very good program.
My question: I have tried to change the colors and therefore I have edited the file jHtmlArea.Editor.css, but nothing happend. I have used the example files, which are included in the download:
css: "jHtmlArea.Editor.css", // Specify a specific CSS file to use for the Editor
By the way, I think it would be good to have a small table in the documenatation which files were needed for a minimal installation and where to put them.
