Dashboard / add several items and time for each

[Marc-pi]

In the admin dashboard, permit to add several items and historize each of them.
this feature should be a changelog area : each time something is changed, admins add a little memo of the changes , admins can use it as a ToDo list
items can be deleted
items can be archived
items can be checked Done

I like designable Dashboard, each module / theme have widget ( block ) for dashboard for some short-cut link or other output , and customizable for each admin
