Way to customize Helium like Arc

Who's implementing?

The problem

Hi everyone,

I don't know if there is a way to customize Helium with pinned favorite, larger verticals tabs & stuff ? Because if I pin a tab, it's like Arc but when I close it, it disapear

Possible solutions

Could be nice to also have a "full vertical mode" ? And pin favorites ?
