This is probably not the best place to make feature requests; better to use the contact form at shoalsummitsolutions.com.
BUT in version 3.0 due out this month, the Game Locations plugin is integrated with the Game Schedules plug, so you can enter the Game Locations and then select them from a pulldown in the Game Schedules. The map links with auto populate on the schedule as well (if you want that).
TEAMS will also be integrated as part of the MSTW Framework. There are some issues to consider since the teams, especially the site's 'home team' will impact a number of areas throughout the framework. I hope to have a v1 of the framework, theme and plugins, pretty solid and published this summer. Definitely before (American) high school football season.
