Either I didn't find this option or it does not exist: it would be cool to be able to display both the logo and the site name simultaneously, I had to code this manually
Same for the site description, you can set it up in Settings->General, but it does not show up in header. Here again, I had to code this manually
Funny: every time I want to adjust the number of Latest listings that show up, I tend to look for this option in Listings->Settings.
Maybe it would be a good idea to move the "Latest listings shown" option from Settings->General to Listings->Settings
