I think the filter search should be improved and expanded to also find the realtracks, realdrums, xtrastyles etc. using the 'Style Filter by: / Filter String' or implement a separate one, something like 'Pack Filter by:' 'Filter String'.

If for example I would type "xtra" in the filter, all the xtra styles should be listed. To search for "xtra 9" only the xtra styles 9 would be listed. Same if I search for number set let say RT 286 or anyone number or pack I have installed.

That would be a real and expanded search feature for the user, without the need for those complex classifications and categories that, although useful for going into detail, are not at all practical for a versatile search. A bit cumbersome to me.
