Ninja
It's not. It's not the same place. It's not the same place at all. Did you watch full video?
Watch my video when I move my mouse to the left side of the logo and wiggle around. This means to look at logo and to left of logo. Then when you click on the other link - you can see the logo moves to the right. It is 100% not in the same position.
It is impossible you did not see that.
The movement of the logo and menu location is in addition to the jerking with page first loads.
The jerking too is another issue. I don't see this on any of the other frameworks.
