I have noticed that Opus passes an MTP device onto Windows Explorer when double left-clicking one, to open an MTP device in Opus I need to right click -> Open in Directory opus
I also have to right click on a MTP device's folder to then open it in Opus instead of being able to open it by double left-clicking one
How to change Opus' behaviour with MTP devices in a similar way to how you can customize Opus' behaviour with certain file types in a file type's "Command" tab?
Does it make a difference changing Preferences / Miscellaneous / Advanced: [Troubleshooting] mtp_enable and restarting (File > Exit Directory Opus; don't just close the windows as that won't restart)?
Unticked Use the Opus implementation for the This PC folder, Opus opens the phone MTP on double click, but still doesn't do anything when double clicking its internal storage or any of the folders on it.
Enabling Use the Opus implementation for the This PC folder again and restarting Opus makes Windows Explorer open the phone on double-click again.
