Osu Songs Marked

The extension shows the already downloaded songs on the https://osu.ppy.sh/p/beatmaplist page as a different color from others. Songs will be marked as downloaded as you download them. Use the settings page to set the already downloaded songs by either pasting a comma-separated list of the song ids or using the folder picker and choosing the /osu!/songs folder (e.g C:\Users\Username\AppData\Local\osu!\Songs).
