I think we might have an advantage if we have something built into CP. Similar to software/OS crash/error reporting, you can attach logs and stuff to the report to make it more helpful.
So in CP, we can generate that debugging info that contains relevant information that users wouldn’t think to report: plugin list, themes, versions, php, etc. This can be a simple “copy this” information, so they include it with a bug report. Or, if we include a form to report a bug inside CP they can opt in to include this information with a bug report. This way every bug report would contain valuable information for troubleshooting.
