In your latest blog post you show pictures of the upcoming interface. It features a new commit history that uses lots of white space.
Please reconsider this decision. Space is a very limited resource on screen, especially if you have to use a laptop screen (on the road, train, etc.). I do get your goal of making the list more readable by adding space around the lines but showing only a small number of lines removes a lot of the context, an information very important in a commit.
