Hi Codeforces,

Like many of you, I spend a lot of time on Codeforces but I have always felt the profile page tells you what you solved, not how you solve.

After a few months of looking at my own submissions manually (rating distribution, weak tags, unsolved problems), I decided to automate the parts I kept checking by hand. I also added two small quality-of-life features along the way: one-click bookmarks on any problem, and auto-fill on the submit page.

The result is CF Analytics Pro a small browser extension that adds analytics to any Codeforces profile.
