Looks good overall.
My personal suggestion: it would be very nice to replace this dark X label on button with some icon.

you about this?

If yes,

not all people fully understand what subsets are that are more than 10 years old. for this reason i decided to draw a symbol that is responsible for the subset. it can be configured through the configuration file and it is different for the old and new search. i also chose the same color that is drawn in the search field
