Regarding The header, I would suggest
– Giving more flexibility in terms of the style like adding a separate controller for the padding from the top or from the bottom, unlike now you are only restricted to the same space from the top and bottom.
– Giving the option where you can edit the Close Button for the mobile menu like make only text or only icon.
– Adding a control panel in the theme settings for the mobile menu where you can edit the style, typography etc.
That would be perfect to see these options available for your theme.
Thank you for
