I love this but could we have skin system similar to osu?

I absolutely adore this minesweeper clone. I love the theming, this should be a standard for all games. It has lovely UI and I can sometimes spend entire hour playing this, it's so cool.

Could we have custom skins? Similar to osu, maybe there would be a folder called Skins where you could upload custom icons/sounds and even fonts. In the theme section, you could then have a drop down to use specific skin instead of the preset ones. That would make it perfect.
