There is no ability in the Notes To Do lists to re-assign a personal To Do item to someone else, or make a Group To Do a personal To Do--this value is set-in-stone upon saving initially the idea.
So, if another person joins the Team and he/she will take on some of your responsibilities you can not delegate some of your personal To Do items. Or, if you are going away, say for maternity leave or out sick for a while, you as the chair person are unable to re-assign the group To Do to yourself. Yes, you can add users to an already existing Group To Do, but you can't add yourself to that task's participant list. The participant can delegate, but not the
This also comes into play if a person leaves a Team and they have several personal To Dos...would be good to be able to re-assign them to the new guy/gal taking over the departed Team member's items, to save a lot of time.
Bulk changes for "All Selected" would be nice too. The Copy Into New -> To Do and resetting tens of entries is quite arduous and counter-productive.
Similiar slightly to Calendaring Administration---which is not in the Linked Idea drop-down, perhaps b/c it's linked already---but at the end-user level.
