I’m working on an idol.st SIFAS card downloader for Linux, which is currently able to download and organize cards and stills in folders.

You can get it here.

This is very WIP and I’m not very proud of the way the code is right now.

It does work, though - and it’s useful if you like to set a wallpaper slideshow of SIFAS cards, as this makes it easier to update the cards.
