Not in filter

Brilliant plugin ! Thanks a ton !

I am using this for category and tag searches, is there any way it can be tweaked to do a “tag/category not in” search as well.

I am not a developer but I opened the php and I saw this comment that says “not in” is on the to do list.

Any pointers on how to achieve this will be really appreciated.

Best
