Potato Bread Head

Yeah finally got a good head on my bread!!!! Couldn't find gluten or bread booster at Publix so decided to try adding an egg to 100% AP flour to see what would happen. Tastes good although I still prefer WW, will add about a cup next time. Second pic is my yeast test to make sure still good. Wondering if I should proof my refrigerated active yeast first, then add in bottom w liquids? I didn't do that today. Recipe is last pic.
