SNAPPS just published some great enhancement modules for Lotus Quickr (Domino):
Favorites is a commonly requested feature for Quickr and exists in the J2EE version but not the Domino version. Consulting companies including SNAPPS have designed interfaces for many companies to have a Favorites feature, but each of these efforts has been unique to the client. Now, we've taken an approach that with one line of code and a single Domino database, enables this enhancement to the Quickr experience for everyone in your organization.
There is also a demo video available on YouTube.
There are more modules to come in the near future:
Modules under development include modules for administrators to more easily administer the server, aggregation modules that will combine data from multiple places, messaging and workflow modules, user activity modules, and modules to manage users across multiple places.
