Celmaro has released a public beta of Webbla 1.5 (http://www.celmaro.com/webbla), a new version of the visual bookmark manager for Mac OS X. Version 1.5 adds support for the social bookmarking web services, Delicious and Pinboard.

Webbla is a standalone bookmarking tool for Mac OS X that automatically creates webpage thumbnails for each added bookmark and displays them in a list or grid view. Bookmarks can be personalized with tags, rating and a description, and organized in collections and smart collections.

The new integrated Delicious and Pinboard adapter synchronize bookmarks in the background and help to organize, share or exchange bookmarks on social bookmarking web services. Webbla 1.5 also introduces a redesigned sidebar that contains a Library, Recent, Collections and Sharing section.

The Recent section offers a new integrated trash functionality designed to make it easier to recover deleted bookmarks. In addition, Webbla 1.5 comes with a optimized grid view to make it faster to scroll, preview, and search bookmarks.

Webbla supports Safari, Camino, Google Chrome, Firefox, Omniweb and Opera with shortcuts and bookmarklets to add, modify and open bookmarks. With the Webbla Safari Extension, it’s also possible to add and modify bookmarks directly from the Safari toolbar.

Webbla 1.5 requires Mac OS X 10.5 or higher. Just remember that beta software is unfinished software, so use with care. Webbla 1.5 may be purchased for US$22.99 and offers a limited, 15-day trial period.
