Hello everyone!

In today's update, we have a couple improvements for the comment section here on Codeforces.

Changing/cancelling votes

It happens sometimes that you click a wrong button, which can be annoying when voting for comments. Now it is possible to change your vote, or cancel it, during the first minute.

Hiding comments

When reading comments it is sometimes useful to hide the comments. Maybe you have already read them, or you don't care about replies to a particular comment. So now you can toggle comment tree visibility with a single click.
