It would be awesome if I could limit the operators available for each field in the QueryBuilder. I'm already providing a dictionary with name and label to define the fields. Could we add in an operators entry in the dictionary that expects an array of operators?
For some of the fields, (e.g. floats and booleans), having IS NULL as the default isn't relevant. It'd be great to be able to limit to just = and !=, or those plus comparators.
