[FEATURE] Sidebery-esque Tree-style tabs #163
Description
Is your feature request related to a problem? Please describe.
I'm stuck in a limbo between vivaldi, zen, and firefox. I need my sidebery workflow, but firefox engine is ass. zen fixes a lot of that, but still struggles with hdr, but no longer supports sidebery or any external tab management for that matter. vivaldi is chromium which is great but there's no chrome version of sidebery.
Describe the solution you'd like
Implement an analog to sidebery built into flow's tab management.
