I hoped to include the HKCU registry reading in this release, but it is still turning out to be annoyingly difficult, enough so that I'm probably going to drop the path I've been on and reimplement differently. However, I've made some progress on UI. I'm assuming there's not a lot of keys to gather from HKCU, so it's currently hardcoded as a list of 10. I'll probably fix that because it would be interested to build the core-side UI by iterating through a loop,but if you have an opinion speak up.
