Previous and next buttons on question page wrong way round?

There are many PHPCS errors in this module. Should I fix them, or should I create a ticket for it?

Both if possible.
Create a new issue as PHPCS warnings are nothing to do with this issue, create a branch, make your fixes and commit and create merge request.

Hi, good point, please fix the PHPCS errors and I will merge it.

Merged! Changes will be added in the next release! Thanks for the comments and commits.

Added to release 1.0.71
