I'm updating from Odoo10ce to Odoo13ce.

Menu tree:
The online quotation v13 does not update the memu tree correcty. Only H2 standard is incoporated in the menu. When you change the size it is not recognized anymore. Also H1 of H3 is not recognized.

Print button:
The print button does not create a pdf from the online quotation. It just creates a pdf of the listed products.

Look & Feel:
v10 had looked a lot better in the top address information section. How can I change this?
Is it possible to import the complete v10 online quotation into v13?
