Все что вижу в инете способы, как всегда установи плагин и будет тебе счастье.
И это правильно: если все функции тащить в ядро — оно лопнет 🙂
Clean, Lean, and Mean
The core of WordPress will always provide a solid array of basic features. It’s designed to be lean and fast and will always stay that way. We are constantly asked «when will X feature be built» or «why isn’t X plugin integrated into the core». The rule of thumb is that the core should provide features that 80% or more of end users will actually appreciate and use. If the next version of WordPress comes with a feature that the majority of users immediately want to turn off, or think they’ll never use, then we’ve blown it. If we stick to the 80% principle then this should never happen.
We are able to do this because we have a very capable theme and plugin system and a fantastic developer community. Different people have different needs, and having the sheer number of quality WordPress plugins and themes allows users to customize their installations to their taste. That should allow all users to find the remaining 20% and make all WordPress features those they appreciate and use.
