folder "tests" necessary?

@kenpachizaraki : Hi,

The folder isn’t necessary for the plugin to function. It’s the test suite used in development to ensure the plugin operates as expected even after changes are made.

You can delete the folder if you wish, but when you update to a newer version of the plugin it’ll get restored. Leaving the folder in place doesn’t pose any real issues for your site.

In the future I plan to omit the packaging of the test folder from the plugin releases.

Cheers!
