Global Delight (http://www.globaldelight.com/) recently revved Voila — its image capturing, annotating and sharing tool for Mac OS X — to version 3.7.1, which improves Retina display capturing and makes a fine tool even more useful.

Voila boasts the ability to capture a region from the screen in rectangular, circular, polygonal or free hand form. The software offers full screen capture, timed capture or menu capture. In addition, Voila is integrated with a blend of annotating tools like texts, arrows, callouts, sprays, stamps and more. You can share your work via email or iPhoto. The software supports web page and webcam captures, an organizer for image management and additional annotations like blur and flip.

Voila can also capture menus, objects, fullscreen or timed captures; you can capture these shapes simultaneously. What's more, you can rotate, resize, switch between captures or undo a selection before capturing.

Let's say you want to capture a web page. Type in the ULR of the page into Voila's built-in browser, and you can snap the current Safari page with a click. Or you can import the web address to snap without leaving your browser. You can browse any web page using the built-in browser and capture the DOM elements. Voila allows you to select more than one DOM element at a time within a web page and snap all of them simultaneously. (DOM, or Document Object Model, is a cross-platform, language-independent convention for representing and interacting with objects in XHML, XHTML and XML documents.)

Voila lets you add metadata to your snaps. You can add titles, relevant tags and describe the information for each of the snaps.

One the most appealing things about Voila is that you can capture multiple screenshots at once. You select different portions of the screen, then adjust, rotate or undo a selection. And - voila! (pun intended) - you can snap simultaneously.

The software sports global keyboard shortcuts to capture full screens, area, windows, web pages, menus and selection captures. You change the keyboard shortcuts in the Voila preferences to meet you needs.

Voila saves all your snaps in a central image library and helps you retrieve your creative works at a later date. If you want to group similar snaps, you can create custom collections and drag images into them.

Voila runs on Mac OS X 10.6.6 or later. It costs US$29.99; a demo is available for download.
