New Shopping Cart Ribbon in Marketpress Sitewide ASAP Please!

Hey there - that new shopping cart button that shows up in the shop area of the site in Marketpress 3 is awesome but doesn't get the user back to the cart to purchase if it's not sitewide. Please make this an option asap. I'm working on a bunch of site edits including reinstating my online shop for an upcoming conference, and this is a pretty big continuity/site design issue.

Bonus points if you guys can add options in the future for styling, like letting site designer pick if it shows up in top right, bottom right, top left, bottom left corner, and background color! See attached screencap for where I'd like to be able to put it...
