sandwhich loaf seed bread fragile crumb

I've been trying to create a reliable recipe and improve my technique so that I can create a daily toast type bread that I can add grains and seeds to and perhaps a small amount of wholemeal or different type of flour (soy, besan etc)

I was happy with my results and improvements in the texture of my bread - as I've posted here in talking about a basic white bread with a good wholey spongy texture.
