One, two, and three are yes. Although the second part of two sort of already exists - the auctions in 'my bids' are ordered by end date, so you'll never have a still-open auction under a closed one.
For number four, if you go to the auction and click on the Creatu's image, it shows all the details. But it would be nice if they were just displayed on the page with everything else.
Number five, try the ACS. ;o
Six, not sure if it'd really be all that useful if you mean on the main bids page. The only time I look to see who bid last is when I've also bid - and if you've already bid once, you'll just look on the 'my bids' page, eh? Number one takes care of that.
Seven, you could always just bid once so you can check back later. And it'd be really annoying if you got an alert every time someone bid. xD People like to bid-war.
Eight, seems a little.. eh. The bidder is the one that's supposed to be keeping an eye on the auction. If everyone was alerted to the auction's near-end at the same time, it'd be madness. xD Just set an alarm or something, if you're afraid you might forget about it.
The ACS one's nice. Definitely make things easier. It wouldn't exactly work for searching natural Creatu, since you'd probably always go over the search limit - but for other colors, it'd work pretty nicely.
