I added some friendlier menus for the letters so you don’t have to go through so many clicks to get to a particular month. In the main menu, there are three levels under the letters, so you can choose a particular month under 1942, for example. Of course, this primarily applies to users on a computer browser or on a tablet in landscape mode. Portrait mode on a tablet or phone always displayed a more detailed menu.
I added a widget in the sidebar that displays all the letter pages—again most useful in a computer browser.
Hope this helps; I know it helps me!
