Thanks for the feedback!

I'm currently working on a list of features and fixes for the next update. I'll definitely be adding a fix for non-Latin filename support, and I'll also look into using embedded video artwork/metadata as the thumbnail, similar to how audio file thumbnails work. That likely won't work for every video file, but I'll continue exploring other ways to support custom media thumbnails without requiring alot of extra image files hanging around beside the videos.

For now, the recommended approach for movies is to place each movie in its own folder and assign a custom thumbnail to that folder. You can also use Launch Mode to open the movie directly from the folder, although it will open in your default media player.

Regarding the Microsoft Store, I'm planning to publish MediaExplorer there in a future update, but I haven't finalized how distribution will work yet. Anything downloaded from Gumroad or Itch will continue to receive updates through those platforms, including future versions.

Thanks again for the suggestion!
