We'll probably look very closely at porting over the Customize drawer (from Universality) as-is (or nearly), since that approach may allow us to support the most features the fastest. But there could be aspects of how personalization was implemented in Universality that don't make complete sense in Respondr, so perhaps some or all of the Customize drawer will be re-designed... even before uP 4.1 is released.
The University of Wisconsin-Madison is pursuing a pretty different idea of how personalization will work in their implementation of Respondr, adding a concept of Favorites that replaces the experience (and is under the hood built on) traditional Layout. Instead of "Add to Layout", with Favorites you "Add to Favorites". This isn't entirely baked yet.
