Jumsoft (http://www.jumsoft.com) has introduced Pro Themes for Keynote, an addition to its selection of premium-quality design themes for Apple’s $19.99 presentation software.

The new themes contain up to 34 master slides — a mix of bullet text and photo-oriented layouts. The Pro Themes collection now includes 20 themes for Keynote. The five new ones range from the clear-cut Dusty Blue to the “colorful and classy” Finesse and the retro-tinged Composure.

The collection requires iWork ’08 or later. Each theme costs US$19.99.
