Many thanks for sharing this plugin with the Moodle community. Please review the validation results and fix all of the issues mentioned. These changes are typically pretty easy to make but if you have any questions just let us know. Here is what shows up currently:
Warning Maturity information ($plugin->maturity) not found in version.php
Warning Release name ($plugin->release) not found in version.php
Please consider adding a screenshot of your plugin to help folks get an idea of what it looks like when installed. I think showing the popup box would be helpful and would encourage adding instructions for getting the mediagallery button on the TinyMCE editor. I was successfully able to install the plugin and it appears to function as expected. Once I played with this I understood better what you meant about the filter. They work hand and hand with each other.
It is encouraged to follow Moodle's coding style as outlined in:
http://docs.moodle.org/dev/Coding_style

Tthe code checker plugin can be quite helpful in fine tuning your code and can be found at:
https://moodle.org/plugins/view.php?plugin=local_codechecker
You may wish to consider using that tool to further improve your plugin. Below, are the initial results:

Total: 28 error(s) and 2 warning(s)
Most of those appear to be whitespace issues so nothing major.
I did mention the question about the icon.svg file that was not being found when the link was created. Overall, it looks good and once we have the issue with https://moodle.org/plugins/view.php?plugin=mod_mediagallery resolved we can get these all approved. Thanks for your speed response to these issues. For now I will mark this as needing more work. Peace - Anthony
Newest version addresses all your issues: version.php, codingstyle, added a screenshot and have updated the README.md with a Post-Install section that explains briefly how to add the button to tinymce.
Are you planning to make this plugin available again with the (big) return of TinyMCE in Moodle 4.1 and later versions?
Best regards.
