This are actually multiple features in one...

The task-completion field does already exists (it's called completed) Curently it is not very nice and should be done into a dropdown-list with percentage-fields. This number could easily be added to task-lists, but I am always fighting for as less columns as possible. So we need a good way of customizing the displays of list. You(!) are a power-user and need those numbers. 80% of the other other users don't and claim streber to be too complicated.

One idea would be to: reports is a topic of it's own that has to be discussed in detail.
