For a while now, verticals tabs have been available in many desktop browsers (including Brave). The tabs UI on the mobile browser (specifically the “card” grid design) makes it difficult to close tabs with just one hand. Orion’s iOS browser support vertical tabs and in particular has a (imo) really great UI design: there is an icon on the navigation bar that, when clicked, brings up a sidebar with a vertical list of tabs (which starts at the bottom of the screen) with an ‘x’ on the very right hand side which makes it very easy to close/manage tabs with one hand.
See screenshot below for what the (1) navigation bar icon and (2) the sidebar/tab browser that pops up look like on my iPhone 15 Pro Max on iOS 18.1:
Would be great if something like this could be implemented in the mobile browser for Brave. I use iOS, but I imagine Android users would also appreciate such a feature.
