Checkpoint checkin. Lots more interesting functionality -- pages can now be set to "single" or "multiple" task handlers, and having "single" removes the task handler arrange UI. Please some serious code re-organization so that Panels can have just one context-based task handler for multiple tasks.

Checkpoint checkin. Partial implementation of page task with generic subtasks, plus revamp of arguments, new access plugins (stolen from Views), updates to the wizard to make it fully compatible with the modal and some minor improvements to make it more flexible.

Add callbacks to the collapsible so that it can be trivially transformed into other things like an accordion. Add accordion functionality to the task admin UI.

Chaos Tools API initial, early checkin. This module provides 4 API tools, plus an early version of the delegator module. See http://views2.logrus.com/overrides for a discussion of delegator.module.
