UI doesn't show up in #Screen tab in Unity 4.6

Unity Engine
1

Hi everyone,
I have just upgraded Unity to version 4.6 and tried to create a button by Create → UI → Button.
However, this button doesn’t show up in #Screen tab but it does in Game tab.
Please look at the screen shoot below:

1364×455 64.5 KB

1350×503 110 KB

Another question is: The default width and height when creating a new button is 160 x 30. When I change the source image with my own image button, I have to change the width and height parameters in rect transform. Is there any faster way to automatically obtain new width and height based on the image which I insert?

Thank you very much!

Zoom out, a lot.

In screen space overlay, one unity unity equals one pixel.

I like to use screen space camera, so you can see it in scene view at the same scale as everything else. Just set your camera:

Now I know where the button in #Screen tab is:

I can’t believe that the camera size is very small compared with canvas size. However, when I am in Game tab, the button is in its correct position ( I still see the button on game tab, it is weird).
Is the Unity 4.6 bug?
