Can I require a feature?

[NetWilliam]

I also use the (codeforces cli)[https://github.com/woshiluo/cf-tool], which has a very interesting feature cf open would just open the problem page you're working on. it's implemented by this lib: https://github.com/skratchdot/open-golang which invokes open on mac, start on windows and xdg-open on linux to open a given url on web browsers.

I think leetcode open pid or leetcode pick pid -o would also be very handy in use
