I would love to have the option to open a file as read-only in PW drive. Currently, you can open a file as read-only in PW explorer. But in PW drive, you can also open a file as read-only if another user has already checked it out. It would be great to make this read-only option available even when the file is checked in.
Thank you for raising this. We will consider it for the next PW Drive release(s). Please note, that Read Only option has been already been added when you are opening a document which is in co-authoring session.
