Works amazing! It's really nostalgic seeing YouTube without all the ugly oversized rounded icons again!
I do have one feature request (If possible): Could you add an option to have the "Your Channel" button on the left side of the screen like it used to be? Edit: Oh well, that's alright. Still a great extension!
Edit: It's possible but, to keep it short, it can't be done easily. As this feature can already be accessed quickly via Avatar button, implementing it properly proves to be not feasible.
