impress.js is not only used for presentations. We might find bugs on the core framework when we are trying to provide custom functionalities for our applications. It's our responsibility to report such bugs using the official Github site. impress.js has an active support forum where people will solve the bugs or new features in core impress.js or their own branched versions of impress.js. Once we identify an issue, first we have to go through the existing and fixed bugs list to see whether it has already been taken into consideration. Otherwise, you will have to report it and look for answers from the people who are using and developing impress.js.
The following screenshot shows us a list of existing and fixed bugs:
All your new ideas and feature requests should be submitted using the http://github.com/bartaz/impress.js/issues/new link. The active issues list can be found at https://github.com/bartaz/impress.js/issues.
