about comments being washed out: in the quest of writing good source code for kids (easy for kids to read, adapt and use) I found that comments should be not only an integral part of the source, but probably not highlighted as a single block, with an uniform color. For kids and beginners, we should have a highlighter for comments that bold words between *, that put some emphasis on titles in comments, that makes function/variable names in comments jump out. Also, we could highlight inline comments (at the end of a line of code, generally frowned upon but potentially useful for beginners and kids) as yellow stickies.
