[Featute request] Bring the old tabs behaviour back

[fabioromeo]

The original Twidere had the best tab behaviour I never saw in any app: it allowed me to put the timeline from each account on its tab, and all I had to do to see each account was to swipe between those tabs. That made browsing incredibly convenient, and I could even set a single tab to receive notifications from all accounts. It was amazing.

Please, bring that back.
