Hi Nate. Thanks for sharing this block with the community. I really like ideas like this - simple yet powerful. I will be happy to approve the plugin once the following issues are fixed.

You state the license of the block is "[CCBY2.0] or better". Not sure what the "better" is supposed to mean, but the best would be to release the plugin explicitly under GNU/GPL3 license. All Moodle plugins are considered as work based in Moodle core code as such, GPL3 applies to them. If interested, please see one of many threads on this topic, such as https://moodle.org/mod/forum/discuss.php?d=135896. The CC-BY is incompatible with GNU/GPL3 (https://www.gnu.org/licenses/license-list.html#ccby).

The recommended boilerplate was not used in the version.php file. The boilerplate is recommended at the beginning of each file and makes explicit the GPL license. You may want to review http://docs.moodle.org/dev/Coding_style#Files to learn more about the boilerplate comments.

Thanks Nate for the new version of the plugin with the licensing issue sorted out. You are cleared to land now. Welcome to the Plugins directory!

This seems to be working perfectly for Moodle 2.9.

Hi Dan, Nate, any idea if it works well in 3.1?

The plugin seems to be working fine for me in 3.1. Any chance one of the contributors could officially confirm this?

We don't have a 3.1 to test this yet, but i can't imagine it wouldn't work. I'll update the meta once i can confirm my expectations. Thanks for the feedback!

Any official update on whether this plugin is supported for Moodle 3.1? It looks really useful. Thanks
