Replaced WP_PLUGIN_URL with plugins_url for better compatibility
Fixed typo in php which broke the Google Console URL in the settings screen
Added error handling to batch query (it returns success even when parts of the batch fail, so we have to now check for individual errors).
Entry will now expand with the time and location even if there is no description.
Removed some unused code.
