In reply to Gary.

Gary, have you considered the idea of “common code” for plug ins and themes?

I absolutely think that idea is worth exploring, it would probably be the most valuable use for the plugin dependencies ideas that get bounced around every now and then, and it's a great place to start thinking about what plugin auto-updates would look like.

There's been some initial exploration into plugin dependencies - if this is relevant to your interests, and you have some time to spare, I imagine the team would appreciate your input. :-)
