Rated 2 out of 5 stars
Great idea, but it breaks the address bar something awful. Whenever the "AwesomeBar" drop-down vanishes, the right-edge split button appears and steals focus.
When I was typing Split Browser to re-locate this page, I got "Split Bro" and then had to reach for my mouse.
It also interfered with my global keybindings somehow, so when I reached for F12 to open my Yakuake terminal, nothing happened. I didn't even think that was possible with Yakuake!
I'll rate it 5 stars when there's a way to completely disable those auto-hiding split buttons so I can just use the context menu for splitting.
