It hadn't crossed my mind before, but this morning I wanted to see if I could merge the content extension and the popup extension into one, and if so, how hard it would be. It turned out to be fairly easy, and took less than an hour. So now I need to decide whether there should be one extension or two... I guess ideally, there would be a single extension with:

• a configuration capability for the user to activate either or both modules; and
• a shared library so that both modules could share functions like the follower network scoring.

That's all over my head right now, though.
