I was travelling and couldn't test it before today. I just updated 
master 1 hour ago.
So, a big thanks for the Ctrl+Space for zoom who definitely change my 
life ... So cool to play with it, thx Arjen.

Here are my observation and feedback :

- Zooming is always centered to the viewport, could it be centered in 
the cursor/mouse position ( the start position when the dragging action 
is performed ) ?
( ex: I start to press Ctrl+Space on keyboard ; I move my cursor hover 
top left , and click to zoom = the zoom is focusing on this zone )

- When pressing Ctrl+Space+click to zoom, if I keep space hold and 
release Ctrl it's not switch to panning , and the zoom continue. I would 
love to can do it.
Same for reverse : While panning with space pressed, I would love to 
only add control to switch to zooming.

With this navigation will be easy and smooth and fast.
Can't wait to play with an improved version.
