Hello, Codeforces!
"Input Copier" by RamiZk is about 6 months ago and he didn't update it . So I decided to write new one with the ability to edit it to suit you!
Any suggestions is very appreciated. If you found a bug please tell me so I can fix it as soon as I can.
How to use it:
Just click on input:
It will turn into red when you click it and it will return white after a second.
Installation:
Tempermonkey extension is required. The source is available in Greasy Fork: Input Copier
Note that Tempermonkey can be installed in almost all browsers.
