Plone Bookmarks
This is similar to the old favourites system in Plone, but using KSS to do it nicely on the client side:
http://kssproject.org/documentation/development-process-with-kss/development-process-with-kss
It creates link objects in the users home folder and sets the remote url of the link to be the page you are on. This might be improved by:
- Maybe not using link objects but storing in a registry somewhere... do we really want favourites to be content items?
- Maybe using UIDs rather than URLs so that things don't break when moved.
We should wrap this up and release as a Plone product
