this is absolutely ok.
I am currently coping all my remaining DVDs to HDD to increase my online collection. As next I will create folders for my Blu-rays and UHD Blu-rays (which I am not planning to copy), and define these as online titles in My Movies as well, so it will be filled automatically with meta data. Afterwards I will move the Collection Mgmt from my Win7 pc to my Win10 pc including HDD and movies, and install MMBrowser as front end.
So I still have a way to go until there and not so much time actually, but I am planning to finish this until June/July.
If MMBrowser would support Offline titles until then (no requirement of a playable media in the folder), I would be more than happy, means of course I will purchase it

I hope that the MMBrowser community will be further growing and more and more functionality can be added. I have some ideas already

Thanks!
Mike
