[New today: Inpaint Brush Tool missing]

Hello, I just bought the Affinity Photo software download today. I've watched the getting started video.  I do not seem to have in Inpaint Brush Tool on my list of tools. 

I made sure I was in a layer and not an adjustment, and not an adjustment layer, as I read in the Help Guide.

 

Do I have to be in a certain layer or adjustment to have the tool viewable? Is there a place to load missing tools?

 

Also, is there a way to load tools or edits across the top on a toolbar, as seen in the video.  I am trying to practice on each of the basic options
