[Suggestion] Better whitelist management?

I've seen lots of people demanding more whitelist spots from time to time.

Since it's not something real, I've tried to manually clean up my whitelist by checking each person and removing people who doesn't still visit the site frequently from it. I'd always do that to free 1 or 2 spots, but was something tiresome to do.

So, today I just made and ran a script to clean up my whitelist, accessing each person's profile to check their last online date and exclude people that didn't visit the site in 2 months or more, so I ended up accessing a thousand pages in a few minutes. Please don't ban me, haha!

Anyway, if you provided this kind of cleanup criteria on the system, I'm sure it'd be also appreciated.

Actually if you just showed the a "last online" column on the whitelist page, it'd already help a lot, for those who manually clean up to open slots when needed, and also for a script like mine, since it wouldn't have to access 1040 pages to perform a cleanup, but just 40 instead! If we could sort it by that, a script wouldn't be even needed in general.

Fun fact: out of 1000 occupied spots on my whitelist, 144 were deleted on that criteria.
