some css help if you can

HI guys!
Great theme. WELL EXECUTED and documented. Got up and running very fast.
I’m going to use this for 3 other directories, and I’ll give you a massive testimonial and you can put them in the gallery. SERIOUSLY, one of the easiest things I’ve ever worked with online!!!!

Couple of assists….Without disrupting the responsive stuff….
1. I’d like to add a left column to the details page, but seems like there is no option for it.
2. How could I make the css for the thumbnail images always roughly a square. I don’t know how to do it in css with responsive themes. If I could get them to be a square across the board, that would be great.
3. how can I make the search bar not go full width, but roughly the width of the map.
4. I want to cut down the spacing between the content and the sidebars on each page,
you can see here. I’d like the sidebars consistent since we advertise in the left one.

I can’t find how to add our logo outside of the CSS
Is there a place I can add the favicon?

Once I get this I can start csv import. Beautiful theme!!
