I do not think the current way to populate the home screen is the best. But, I haven't seen anything that is really better. I would prefer not to loose the book I am reading from the home screen, but, at the same time, if I load or purchase five new books, I think they should be in my face and obvious.
Adding alternate views is good idea. But, I don't think that will happen. Kobo have shown no interest in doing it. And as I said, there are more important things, to me anyway, to do. I want a Series list and an Authors list. These will help me to manage my books on the device a lot more than the changes you suggest. And adding filtering to the library lists would add as much again. And there are some bugs with I really want fixed.
