Thank you for contacting us.
Below are the answers to your questions.
1. Unfortunately, this cannot be achieved. There is no way to identify in which AutoHide
area the Pane should go when is floating or in document host. This is why we haven't implemented that feature.
2. To hide the "x" button and to disable the closing of the Pane you can use the property CanUserClose
3. To customize the header of the Panes you can use a custom theme. Attached you will find a sample project which illustrates different way of customizing the header: color, adding an icon, font, etc.
Could you please clarify what else you want to customize. Sending a screenshot will be very helpful.
Looking forward to your reply.
