Coding in the OPML Editor 
Things I Like About Coding in the OPML Editor
the structure of code is easy to see and follow
re-arranging code blocks is easy
a useful debugger is built in to the editor
most of the tool is written in itself
I can see sourcecode for most of the built-in "verbs"
Things I Don't Like About Coding in the OPML Editor
No syntax highlighting
No code-completion
No live syntax checking / typeo prevention
text rendering "feels" off compared with other text editors
text typing and keyboard navigation is a bit slow
The undo buffer only goes back one edit
no support for source control systems (svn, git, etc.)
