The style list has the following problems :

• should be a gallery when opening
• the text of the list is editable for completion : think about removing this stuff
• when choosing something, the cursor is set inside the liste and do not go back to the editor
• the text of the box do not reflact the selection
• changing text without selection do not work
• changing text with selection works too much (when the return key is set, the style may be still applied)
