Redesign with version 4 is a step back

I really like the app, but the redesign of the app with v4 extremely reduced the usability for me. I am not interested to see the map on the main screen at all - i can be only at one place at the same time. if i am interested in more than place, i have the list of places, so no need for the map as main element of the main screen. I used the history diagrams quite often, but the new style is kind of hard to read - i am not a UI designer, but with the old version it was much easier to catch the information quickly. Is there any way to revert to last 3.x version?
