Orion currently doesnt implement it this way. orion has tabs 1 and 2 swapped in the first image.
instead, orion has it this way:

this means that when you swipe to the left on
this also results in a very weird UX as show in this video:
if you start on the kagi tab, and swipe to view the tab to the right, that tab is actually shown as being on the left in tab overview.
Orion, OS version; hardware type:
ios 16.3.1
