Love Onetab, but not a fan of the most recent update. Not sure why they changed it to this forced center-aligned layout with no ability to change it to something like previous versions, but it makes for a ton of wasted space on either side on my 1440p monitor. I also have the bug with Onetab auto-pinning its own tab every time it opens but they've mentioned they'll fix that soon, at least. Reverted to an older version for now.
