What's New in Plone 2.0 - Usability Improvements
Easier to publish
Plone 2 makes it easier to publish items and change the workflow states of your content. An always-available pull-down menu streamlines the procedure for reviewers and other roles that deal with workflow changes.
Easier to add
Plone 2 also makes the creation of new content much more accessible - a pull-down menu with the available content types is included everywhere content can be added.
Easier Collaboration: Item-level Sharing
In addition to the folder-level sharing of content available in the previous version, Plone 2 adds item-level sharing - so you can now share single documents and other content without making the entire folder shared.
Easier Collaboration: Sharing by Groups
With the new groups support, an item or folder can be shared with a group, allowing easy implementation of natural collaboration patterns.
