Flexable Filters

In the Filters window, instead of giving a list of selectables to add just for “receive” give us the ability to add a field, example: “To:” and give the ability to enter specifics or wild card characters. If not then add another window for this type of selections and if we use this then the other will be disabled so there is not conflict. The other fields (From:, Subject:, Body:, et ceteras) should be selectable as well.
