I don't use the default layout for my reading plans. If I click on them from the ribbon, I get the very busy set of panels that is the default. I do inductive study and so a lot of up front, non-Bible research isn't what I'm looking for and just crowds up my page and slows down my interface. I've also had a few concussions (too much ice hockey!) and all the scrolling gives me a slight headache. 
I have set up a layout for each reading plan - Bible in a Year, Book of Daniel Study, Ethics reading and Greek study. I open them manually from layouts instead of using my ribbon.
I would like very much to be able to designate a layout to go with my reading plan. If I set up a nice layout and then create a reading plan for it, I'd like to choose, in the reading plan setup, "default" or one of my own layouts to come up when I use the ribbon.
Enough wishlisting! Plenty of software testing to do at my own job today. TWO new releases at once. :-)
