Too often doors and other objects are visible on levels below where I do not want to see them, for example, door swings visible below roofs. While it is possible to filter doors by level a specific level must be chosen by name! This makes the filter impossible to use in a template that is applied to views on different levels, and since filters must be chosen as an included or not included class within a view template, a level specific filter cannot be applied to any view controlled by a template with other filters active. We need the ability to select the <current level> as an option for Below or Does Not Equal rules.
