I think one Include/exclude bar is not enough. It severely limits the possibilities, for example when I have brand keyword in domain, and I'd like exclude all brand keywords, then I cannot put additional filters on URL because it will give me 0 results because of the brand. I'd like to suggest to create button "+add target" (the same as you can see in Content Gap) that would add more include/exclude bars so we are able to make more operations and add more filters on the keywords and URLs that would not break the results.
