Thanks to Brett Terpstra I recently discovered PopClip, a utility that recreates iOS’s popover behavior on the Mac. When you select text in just about any app or field, a popover appears with a customizable set of options ranging from Google Translate to “send to OmniFocus” to “track this package” to a growing list of over 100 other apps and services.
PopClip is fantastic. Get it.

To no one’s surprise, Brett has now created a PopClip utility called PopMaker, which lets you create your own extensions. PopMaker is in early stages right now and limited to creating “search” and “surround” options, but knowing Brett, there’s a good chance he’ll iterate, polish, and expand PopMaker if enough folks show interest.
