Answer 2

I'd try the following:

• implement a TagEditor, which has the functionality to edit a single Tag (based on an AutoComplete TextBox that is swapped with a TextBlock once an existing Tag has been recognized or editing is ended)

• create an DataTemplate that uses the TagEditor

• create an ItemsControl that utilizes the DataTemplate

that breaks it down to three challenges, of which only the first is a bit tricky, but solveable with the given keywords and stackoverflow ;-)
