Explain the problem as you see it
When you extend a supertag, the fields from the inherited supertag are placed above the fields you introduce in the child class.
Why is this a problem for you?
This is a problem because I have specific fields that I would like to always be on the bottom of the child supertag, but now that field is somewhere in the middle, depending on how many fields are introduced by the child supertag.
Suggest a solution
Provide the ability to organize all fields on a supertag as you wish instead of the hierarchical approach.
