Feature request: Add buttons for zooming

[ufechner7]

For a beginner it is not obvious how to zoom. What would help:

• [ ] add buttons zoom in, zoom out, home (initial size)
• [ ] add a help entry in the menu that explains the key and mouse bindings

I'm not sure I really want buttons for zoom in/zoom out since:

• I'm trying to minimize screen waste, and maximize plot size.
• I don't particularly like how those buttons work out in PyPlot/matplotlib.

That said, I do like the idea of having a help window to explain the mouse/key bindings. ...I just don't see me working on it for a little while.

I will keep it on my list of things to do, though. It is a good idea.

Thanks.

You write: "I'm trying to minimize screen waste, and maximize plot size." Well, they could be optional, default: off
