Can I Have a Thumbnail View (Small Preview Box)?
Is there a way to have a real-time updating preview box (or thumbnail view) so that while I'm zoomed in, I can see how what I'm working on looks at its full view? Does any tool like this exist in Photoshop?
This question is probably confusing, so what I'm talking about is this kind of feature that exists in Paint called the Thumbnail View:

Paint Tool Sai also has this feature:

I ask because I'm working on some pixel art and it's really annoying to have to keep hitting Ctrl+1 whenever I want to see it at its full size, then have to zoom all the way back in to get back to work. It seems like a no-brainer for Photoshop to have this feature, but I can't find it. It's also a hard topic to search for since "Thumbnail View" in Photoshop usually refers to layer thumbnails or file icons.
