ZipList is a free online shopping list and recipe service that makes it easy to share and add ingredients with one click.

ZipList gives you the tools to create, store and share a family grocery shopping list on the web. The list can be accessed by almost any device with a web browser, or you can share it in an e-mail or SMS text message. Of course, you can also print out an old-fashioned paper list if you prefer that.

The web-based shopping list interface lets you specify which store an item is available at — you can even specify the aisle. There’s also an option to add notes about coupons or anything else that’s pertinent to whichever household member goes to the store to pick the groceries up.

ZipList hosts a recipe database with hundreds of thousands of dishes thanks to an integration partnership with Martha Stewart Living Omnimedia at MarthaStewart.com. You can pull a recipe out of the database, identify it as one you plan to make, and add the items to your virtual shopping list.

If you want to pull a recipe from somewhere else on the web, ZipList provides a Recipe Clipper bookmarklet that lets you do exactly that. Again, ingredients for the recipe will be added to your shopping list.

The ZipList website is free and ad-supported. ZipList also powers Martha Stewart’s Everyday Food: Fresh & Easy Recipes iPhone app [iTunes link], which costs $0.99.

Gmail has officially integrated several of our favorite Labs-only features into Gmail proper, including previously mentioned features like search autocomplete, Go to Label (one of the biggies in my Gmail master redux), forgotten attachment detector, YouTube previews, and more.

Search autocomplete automatically suggests search criteria based on common searches; Go to Label adds excellent keyboard shortcuts for navigating your account (type ‘g’ + ‘label name’); forgotten attachment detector alerts you before you send an attachment-less message that appears to promise one; YouTube preview, like it sounds, lets you watch linked videos inside Gmail without opening a new window; custom label colors lets you set any color to any label; and the vacation dates feature lets you set the dates you’ll be away so your auto-responders don’t go out before or after your vacation begins or ends.

On the flip side, Gmail also retired five less popular features: Muzzle, Fixed Width Font, Email Addict, Location in Signature, and Random Signature.

Got another Labs feature you’d like to see graduate Labs and join the default Gmail feature set? Got one you’d like to see retired? Let’s hear it in the comments.
