- Add taskId parameter to createStack() so stacks are pre-populated with a task. - Keep track of stack access order in DisplayContent so getTasks returns in MRU order. - Set touchableRegion in InputMonitor so modal touching does not extend beyond stack boundary. - Fix stack merging so that deleting a stack results in a new stack the size of the two children.
