What is the proposed idea/solution?
Currently the filters in Interface for a Boolean filter is limited to "is". The user does not have the option to "ignore the field" by leaving it unchecked . Unchecked pulls up all unchecked records, checked pulls up all checked records. This is too rigid of an option and causes user to get confused by the records they see when they don't check the box in the filter. When you press the "reset" link next to the filter, the user thinks they are seeing all the records when, in fact, they are seeing only the unchecked records.
The solution would be to have 2 options for the modifier "is" and "any". The checkbox is grayed out or hidden if the user selects the "any" modifier.
