Search sectors/items/linedefs by settings

Okay, here's a kind of suggestion (as well as a thinly-veiled confession). Whenever I get stuck looking for secrets, I often resort to DB64 to search for those I haven't found yet. However, I often have difficult times because there's no option that lets you search sectors and/or items tagged as secret(s).

I think it'd be such a useful and handy feature for both mappers and players alike.
