If tabs in Figma are the top (cause they have higher hierarchy) then why is the toolbar (which has also higher hierarchy) have been placed at the bottom of the screen. It makes no logical sense. Now the user will have to jump up and down. If you want to make things according to your “logic: all should be at the bottom” → then put tabs also at the bottom.
Logic has to be consistent. Or give user freedom to bring toolbar back at the top. Or place tabs also at the bottom.
