Hi everyone, I just published AtCoder Analytics, a Chrome extension that adds extra stats to AtCoder user profile pages.

I started this because I noticed another AtCoder-related extension I used stopped working (likely due to site/API changes), so I decided to build a lightweight alternative and publish it.

Features

• Solved-by-difficulty histogram (estimated difficulty)
• Solved breakdown by contest series (ABC/ARC/AGC/AHC/etc.)
• Unsolved list (with links)

Feedback and bug reports are welcome.
