Hi @sunlight1976,
Thanks for pointing this out. I have made some changes to the development version of the plugin, which now allows for Editors to manage Maps and Collections. The capabilities are now:
Maps: requires edit_posts
capability.
Collections: requires manage_categories
capability.
Settings: requires manage_options
capability (unchanged).
Please see this support page for more details on role and capabilities. In the future I may add some settings to give greater control over this.
You can download the development version of the plugin here. In order to install this version you will need to either manually install it, or use a plugin that allows you to upload it through the WP Admin.
Please let me know if this does not resolve this for you.
Thanks,
Joe
