Fields editor

[Lemour-sudo]

Is there a fields editor that can allow users to dynamically create and edit their fields such that they can be available in the query builder?
I do see a way of manually doing this such that I can use forms that will update the fields that are used in the query builder - I am not sure if this will work and if there is an existing solution already.
