First of all, thank you for creating a brilliant plugin! I have started using it for my site - and have a few suggestions for next version:
1) Sort/search by location
- Is it possible to search or sort by location? This will be particularly useful for a Buddypress social network site members, allowing them to see if there are other members within the vicinity
2) Listing of most popular check-in locations
- A page or widget listing the most checked-in locations
Hope you'll consider them and keep up the good work!
