You should be able to sort opportunities by location. Definitely by state or even better city and state.
You can "filter" them by city and state, but you can't sort them. And this info is also not in the Opportunity Card Fields. :-(
I am sure I am not alone in that I have many open opportunities across the country, and it would make it so much easier to be able to "Sort" them by geographic location to get a birds-eye view of where your current open opportunities are.
Currently, your only choice is to use Filters and keep going in and out to change the filter to see just those opportunities.
If you added the city and state to the card fields, you can then "sort" them to see how many open opportunities are in each geographic location all in 1 screen.
This doesn't seem like a heavy lift for programming to achieve
