When you create a field in the xmldb editor you have to select all the options. It would be good to have a one-click way (well, type in field name and comment, then one-click) to create Moodle standard fields such as varchar(255), text, and int(10) with all the usual modifiers on that. This especially applies to novice developers.

Maybe a Javascript button that initialises all the fields below so you can still customise if needed?
