After capturing your image or video, it is sent to the Voila Editor, which has a large selection of vector drawing and effects tools to edit and annotate your images. You'll find the expected drawing, text, arrow, and callout tools, as well as special effects to add the appearance of torn edges to shots, color filters and adjustment, and region highlighting. Selecting an image in the scrolling library area at the bottom of the window brings it to the editing pane. Each image annotation is kept on its own layer, and you can move layers forward and backward.
The Editor works well for the most part, but I found a bug with the paint tool that kept transparent areas from being correctly filled. The company acknowledged the problem, provided a workaround, and says it is working on a fix. I also ran into a handful of other cosmetic bugs, indicating to me that the program needs a bit more quality assurance polishing. One small drawback to the Editor is that you must use it; you can't save shots directly to disk. I'd like the option to skip the Editor and have the Save As dialog appear immediately after capture.
You can add and edit a capture's metadata in the Information pane to the right of the editing window. Besides useful information such as dimensions and file size, you can categorize the capture and add custom tags and a description, to help keep screenshots organized.
The Voila Editor provides a unique and very useful Organizer tab that I haven't seen in competing programs. The Organizer allows you to group your captures into manual and Smart Collections. The program comes with many premade Smart Collections for different kinds of captures and capture destinations. You can create your own Smart Collections, grouping together custom tags you apply to screenshots. This is great for projects that might require you to keep many screenshots in different folders; with Smart Collections and tags, you can still easily review all the screenshots in the project for consistency.
You can share any capture in the editor by dragging and dropping it to the Desktop or other destination, and you can choose the default sharing file format. You can export captures to iPhoto, email, and many online destinations, including FTP/SFTP, Flickr, YouTube, Dropbox, Evernote, and Tumblr, but notably excluding Twitter and Facebook.
Voila is available from the Mac App Store or the Global Delight website for $30. This is $20 less than Snagit, though the Snagit Mac price includes a license to its Windows version, a significant benefit if you have cross-platform needs. But if all you care about is Mac screenshots, Voila is a good value. Once it is a little more polished, eliminating its niggling bugs, it will be an excellent value.
