This is just a little navigation/ user friendliness request.
I'm very familiar with Adobe products and as a result it's second nature for me to use the back and forward buttons on my mouse to scroll left and right. I currently use a Magic Mouse on my iMac and I'm not sure if this functionality exists for regular mice or at all but it'd be really helpful when I am navigating around my pattern piece.
Regarding zooming in/ out/ fitting pattern piece to the screen using cmd +/ -/ 0, I notice that it behaves a little strangely. Sometimes it works, sometimes not at all.
These are just small things but would improve my navigating around the interface. (Not a high priority but would be nice!)
