So if we've received multiple PMs we can go immediately to the next one without clicking on "Inbox" first.

If you hit the "back" tab it only takes one more click to go to the next PM. Those extra clicks are the price to pay for being such a popular monger (replaced hobbyist), lol.

But this site is unique in not having a "next" button and requiring you to use two clicks instead of one to get to the next PM.  It's just stupid.

so we can search using keywords and such... I got pms sitting there from 2004, when I was just a bumbling moron...lol

Yeah, yeah, I know you have suggested it and I backed it a few times. I can live without nick's "next" feature but a search capability by sender, recipient, and subject, sure would be nice.
