1. An undo button would be nice
2. I can’t get out of edit mode. How can I switch back to viewing mode?
3. Highlight LaTeX syntax so users can easily distinguish code from text.
4. Add info to buttons when mouse cursor passes over.
5. How do I add a new paragraph? Are paragraphs gone forever? In older articles started with the previous editor it is hard to distinguish the active paragraph (the one being edited) from other paragraphs.
