Right - "sorta-kinda" is already provided embedded within the hard-to-use CMS user interface which is intended to be used by content providers, editors, etc.
It would be nice to have some way to access the CR browser portion of the CMS without having to work through the rest of the CMS proper because people find the CMS's UI hard to use.
I don't think there's really any code here to right, it's more a case of intelligent theft of what already exists and figuring out some way to make use of it without having to physically make two copies of it.
And perhaps enhancing it ...
Note that none of the CR client packages other than the CMS system currently use the CR's ability to map templates to CR types and individual items to do their display. Everything's done manually (outside of ETP which has its own way of doing this rather than use the CR's way, sigh)
The entire suite of packages using the CR are ripe for massive cleaning-up and regularization.
