This custom field suite plugin is great, but it leaves a few things to wish for.
1. Instead of displaying the field name (which should only be used internally in the code) it should instead display the field label which is much more readable and gives some more information than the rather bulky field titles.
2. I've noticed a tiny bug when switching from checkbox to popup menu, the data entered in the checkbox is stored in the database and displayed as such.
The checkboxes could be displaying true / false, no / yes instead of just displaying 0 / 1. Remember that we're dealing with regular users who maybe doesn't have as much experience when it comes to programming, so why not make the step as easy for them as possible?
Apart from these thoughts a really good plugin!
