just an idea but i'd think it would be great to have this built in. a scanner that would scan your current xenforo installation and find any plugins, template mods, themes, that may be incompatible with each other or an upgrade to a new release of xenforo. would help save users time uninstalling, disabling & checking through all there addons which may cause damage to the next upgrade of xenforo or break the upgrade installation process. after scan completes it should give you options to disable or uninstall the plugins that may cause issues or any custom made template modifications and recommend you remove them for the time being. and would be great in Troubleshooting if your site is Unresponsive due to a plugin. sure disabling add ones one by one, is one method but a scanner that could detect the most probable cause could also go a long way. i got this inspired idea from a iOS jailbreak tweak Called Crash Reporter it detects and scans through logs and finds the most probable cause of why a process died or what may be interfering with the operation of your device.
