I don't know about anyone else, but I really like the ability to search auctions and what not. I use auctioneer, its seems to work really well for me, and sometimes I make alittle extra money. Maybe I just don't know enough about AHsearch, and AH_ShowBid, but it seems to me there very limited.
Is auctioneer gonna be a possiblility, or is this just too involved, I know your goal is to keep MazzleUI compact, yet versitile with many options and addons. Maybe auctioneer will slow MazzleUI down.
Anyways thats my 2 cents.
