Feature requests

Hi,

Thank a lot for this amazing application. As a Magic card collector it helps me a lot to record all the cards I have and the one I am still missing.

I have a feature request : Would it be possible to add an option to better see cards already in the collection. A screenshot of what I have in mind :

Color the owned card with a semi transparent square. Color match the one choosed in patreon option.

Would help a lot on the mobile version of the app.

Thanks a lot !
