I hope that there is a way to remove the sorting by category of filters in the Filters menu. If not, it is a feature wish of mine. It seems I always start out scanning through the wrong category to find the filter I want. If I start out looking in the Stylistic category, it is sure to be in the Creative category and vice versa. At first I kept searching all categories in vain for the Frames filter until I finally learned to remember that it is called DIGITAL Frame and is sorted under D and not F.
Not sure if this will help but if you favourite some of the filters you can use that tab ( FAVORITE) to more easily see the filters
or can use the RECENT tab to see the filters you most recently used without them being categorised.
