Maximize display still shows list expand bar

Hi,

When in "No switch mode" display mode (i.e. item list is hidden when slecting an item from a list (e.g. meetings)), I user goes into "Maximize" mode for text editing, the text editor still show the (what I'm calling) list expand bar:

This bar actually:
- hides text editor buttons
- if selected (if user clicks on this bar intentionally or unintentionallly), the overall projeqtor display falls back into a (I guess) legacy display mode
