Sider 0.5 Technology Release is ready for download. It's just a demo of the platform and comes with a limited number of extensions. It also has a time-limit and will expire on 04/01/2006. If you decide to check it out, please, write us about your experience.
This release is just the first step toward completing Sider. We will continue to work, adding new features and support for different types of documents to ensure it is well suited to work with different information. Our current focus is adding support to manage notes and projects.
