You don't maximize windows except to watch videos at that size. It's more like having multiple monitors with fluid borders. You focus as needed, leaving the rest in your peripheral vision. That said I did miss maximizing windows to focus on tasks.
yeah key binds to move windows around is a must for me
Aquasnap for Windows users has been great (it's a tiling window manager). Worth the ~30USD.
I use a combination of Aquasnap's magnetic border feature with MS Power Toys hotkeys and it has been a treat. Still room for improvement tho', esp. if I can force specific browser tabs into particular windows based on purpose.
