Steam Big Picture mode.
Its right there right next to large mode, which you need to use to browse the store.
and every time, I hit big picture mode instead.
and have to sit through the stupid animation, then try to remember how to put it back in regular mode.
and I dont understand why they cant give us an option to disable big picture mode. Its only useful for a niche minority of users, let them have it without becoming a headache for the rest of us.
and make steam remember fucking window sizes and positions while you''re at it, fucking valve. every goddamn steam update just makes the performance and usability worse.
