Please keep the issue tracker limited to bug reports.
If you have questions about how to use reveal.js the best place to ask is in the Discussions. Anything that isn't a bug report should be posted as a dicussion instead.
When reporting a bug make sure to include information about which browser and operating system you are on as well as the necessary steps to reproduce the issue. If possible please include a link to a sample presentation where the bug can be tested.
Please do not submit plugins as pull requests. They should be maintained in their own separate repository. More information here: https://github.com/hakimel/reveal.js/wiki/Plugin-Guidelines
