I’ve made a Google Chrome extension that allows you to follow your friends on Timus. To add a user to your friend list, click on the star icon next to their name. Like on Codeforces, friending is not mutual.
Get the extension from the Chrome Web Store.
Source code: https://github.com/slava-sh/timus-friends.
My announcement has left the “recent actions” sidebar. I believe there are still people who would use the extension but haven’t seen the announcement yet, so here is my bump.
I encourage everyone to share their thoughts about the Timus Friends extension.
