Push notifications are one of the very important things about platforms like codeforces, but for some reason, they don't exist. Yes, there is a bell icon in the upper right corner, but this is not enough, because it is not very noticeable, when notified, it only changes color. But this is not the point of the blog, I wanted to convey to the developers that push notifications are very necessary for users not only for personal chats, but also to see everything that happens: a comment under your blog, a reply to your comment, adding/decreasing ratings, etc.

I hope this blog will not be ignored by the developers. As always, thanks to MikeMirzayanov for the codeforces and polygon platforms.
