Evernote continues to roll out improvements to its note-taking and storage app regularly, and while Evernote says that it normally doesn't promote Beta versions, the features in this update are among its most requested. Evernote 2.0 Beta for Mac adds in-app notebook sharing, as well as a new organization feature, Notebook Stacks.
Before today, sharing Notebooks meant using the Web version of Evernote. But with this update, it all can be done within the desktop client.
There's now a new tab in the left panel, splitting your notes and those you've shared. You can set the sharing to public so that anyone can view or you can invite individuals and groups to the notes. You can also establish whether or not you'll require people to sign in to Evernote in order to view them. You can establish how frequently you'd like the app to check for updates and sync these linked notebooks.
Shared notes can be edited by those you've invited only if you have a Premium account. Premium Evernote subscribers also have access to note history for these shared notebooks, so you can view all the changes that have been made.
If you're an avid Evernote user (like me), have a lot of notebooks (like me), and are methodical about your filing system (that's me too), then the second feature in this update will make you happy. You can finally "stack" your notebooks in Evernote, so you can group together and better organize certain notebooks - a good feature for those who use some of the apps in Evernote's Trunk such as Awesome Note.
In order to get this version, click on the "Update to Beta" checkbox in the Software Update Tab in Evernote for Mac preferences. But remember: it is Beta, a "work-in-progress."
