The functionality new filter input field is not recognizable at all
There is a new input field to filter pages in the page tree below it,
a) there is no description or help available and the current look and feel reminds me of a searchbox or maybe a zoom rather than a filter.
b) the design is completely different from the rest of the backend forms
IMHO this should be redesigned and there should be at least some additional information about the functionality.
