As someone who does not like to use boolean, and knows plenty of people who feel the same way...I support this as an additional option. Boolean operators would still work, so it's not taking anything away from people who enjoy it. For those who don't want to use boolean tho, it limits and diminishes the users experience. That said.. we'll are buried in an over saturated texture market, which is growing astronomically with PBR and AI. I don't want to write a book of operators in my search field, just to exclude those options when I'm looking for socks. It'd be for more accessible to check boxes, (and have them stay checked) and move on. Use it still if that's how you prefer, but boolean shouldn't be the 'go-to' to get more refined search, it doesn't fit everyone.

Er..... don't we HAVE that already? I mean, I use it all the time:

keyword1 NOT keyword2

The trick is to write the NOT (or AND or OR) in all caps.
