[Remove white background via Blending Options (Affinity Photo)]

Perfect. "Erase White Paper" did the trick. Thanks.

[Quick Newb question - Finding open files]

I just started using Affinty Photo today.  When I have multiple photos open, I am accustomed to seeing them under the "Window" tab.  I only have one file showing in the "Window" tab at any given time, but I have multiple files open and I have to close a photo before I can get back to the other open items.  How do I flip back and forth between open photos/projects?

 

(I'm sure it's painfully simple, but I haven't figured it out...)

 

Thanks
