Is it sufficient to only be able to filter by the exact KEV date? I can imagine users want to do a weekly search to find out "which findings where added to KEV since last week"?
I also realize adding before/after fields may clutter the UI more.

Yeah good point! I've added before/after filters for it. Does add a bit more to the UI, but it's already got a lot there so maybe it's not too much? Let me know what you think, and thanks for pointing this out, I think these are very useful.
