The basic skeleton is in - You can create your own plugins (my alpha has uTorrent, Foobar and Winamp working) and choose a different theme\layout for each plugin, as well as for each application its going to be pasted in (for example, you might want to add color codes for mIRC, but forum BB codes if you're pasting in your browser, etc).
You configure each plugin's options and default theme\layout, choose a shortcut key, and add any app-specific layouts if you wish. What's NOT working right now is automatic pasting (as in, now you need to press your own shortcut key, and then paste it yourself from the clipboard) and i have found no way to support MPC and eMule decently.
