I've created a couple of collections of Thunderbird add-ons:
If anyone's got any suggestions for any additions to the tester
tools, I'd be happy to consider them.
Part of the intention for these collections is to display them in
the main part of the Get Add-ons pane on the new Add-ons Manager on
trunk. These will be for highlighting to nightly/alpha/beta users.
We'll be considering what collections we want to promote in release
builds closer to release time.
