I'm also a bit concerned about the responsiveness of https://ui.mantine.dev/category/headers/
There are breakpoints where the elements are in a weird state / position and the hamburger menu doesn't seem to work. The tabs example doesn't do anything on mobile for example. Was about to dive in, but now hesitant to commit.
