Is it possible to modify a Theme?

I am using Bold(Dark) Theme. I like the theme and looks good. I want to know is it possible to modify Theme like Dark Theme where the Header sticks inline with Menu Icon as given in screenshot. I want 2nd screen like design.

Also is it possible to remove the ALL-FAVOURITES tab. I am planning to have a separate common Fav screen instead on all screens.

Try removing the favorite button from your items to see if it fixes the problem.

About the design, best you can do is CSS in a details layout.

I want the Favourite icon to be there but doesn’t want the tab’s.
Any pointers for CSS in Glide?

Then you can try showing it in a Details view, use an inline list. It will not show the favorites tab.

CSS is not officially supported, probably @Christophe_HK can give you some pointers about what to put in the rich text.
