Seahorse2 is moving over to the original seahorse project in order to lessen confusion and whatever. Check there for updates.
Moved the project to alpha status, am now working on key/ring display and editing. See the most recent TODO in the tarball or cvs for details. 0.2.0 _should_ have almost all key functionality provided by gpgme
For anyone that somehow wanders here, just wanted to let you know what the current status is:
I'm designing the interface of the main program (not key manager) using glade-2. It will be similar to seahorse's design, but I'm going to try to make it more intuitive, simpler, and easier. When I have the interface done, along with basic operations (no encryption), I will upload it. Let me know if you've got any interface suggestions.
