Very simple extension to hide/show problems tags
This is a very simple extension for the Codeforces website. It allows you to Hide/Show problems' tags in an easier way (i.e. instead of changing your settings every time).
This extension just adds some buttons to Hide/Show the problems' tags whenever you want.
By default, the tags will be hidden.
To use this extension, be sure that you DID select the option "Show tags for unsolved problems" in the settings of your account.
