It’s been a while since my first post on the Activity Manager for Thunderbird. There was a lot of positive feedback from an Activity Manager talk we gave in Barcelona for the EU Mozcamp. And since that time there has been quite a bit of progress on the Activity Manager code.
Emre recently landed a new “work in progress” patch ( check out the patch in bug 257942 ). Also there has been a lot of work put into documenting the Activity Manger Interfaces to help other developers properly hook into it and use it. Please take a look over the interface docs and if you’re so inclined you could grab the patch and apply to a current release, beta or later, to see the current activity manager in action.
Beta 1 Released
