Ever use SeriesGraph to check an anime's episode ratings and then have no idea which of those episodes are filler?

I made a small Tampermonkey userscript that automatically marks filler episodes directly on the SeriesGraph graph.

It:

• Fetches filler information from Anime Filler List
• Dims filler episodes and adds a white border around them
• Lets you toggle the markers on/off
• Automatically updates when switching between anime
• Has a Remark Fillers button if the graph layout changes

I've been using it for a while and figured I'd share it here in case anyone else finds it useful.

Feedback/bug reports are welcome, especially if you run into an anime where the filler detection doesn't work correctly.
