The problem
when you are writing a contribution in utopian box you will see this option
but while i was using my android phone or even while i use utopian from my laptop i find it difficult sometimes to go back and fix the error that you made suddenly or if you put a link or photo in the wrong place
suggestion
i suggest to add a return button (undo/redo) option in this menu to make it easier for the contributors to edit and fix their contributions
conclusion
adding this feature will help a lot especially the people who use phone because when you use a laptop you can do CTRL+Z to go back but in phones this can not be used.
