As C.Boemann already said, we met at my place for two days in order to fix some serious issues we had with the undo/redo framework in Calligra Words (and Stage for that matter).

Since Monday, a feature I have been working on for quite a while has been merged into Calligra master. This is the style selection combo box.
Until Monday, the style selection widget was a home brewed widget based on QFrame. It wasn't optimal and that is a British understatement. Now this widget is still home brewed, but based on a QComboBox.
