Is it possible to restore default viewport condition? This is default viewport condition after I made a '2d animation' project by ctrl+n.

And I scrolled mouse-middle button to zoom out viewport.
Then I wanted to restore default viewport condition(not similar but exactly same as first picture ) but I could not.
How can I do it?
File&gt;Defaults&gt;Load Factory Settings. This will reset everything, like your addons, custom startup file too.
