Found a plugin for the lazy Custom Post Widget, this plugin allows you to display arbitrary content in a special widget block. Simply put, we can create our own widgets from the admin panel in a couple of mouse clicks..

For a simple output, I would advise using the standard text widget, but if, for example, you want to display a video and add text to it, then with this plugin you can first prepare everything in the standard wysiwyg editor. Next, save this content, giving it a name and displaying it through a special widget.

Pretty handy if you need to create a website in a hurry, for example for those cases, when the site is closed from indexing and you don’t care what the general code looks like. However, I did not look at the code, perhaps quite a nice and useful plugin ).

It's also helpful, if you are making a website and you need to give users access to change the content of a separate widget, there is no such possibility in the standard text widget. And those, who will change the content, can do it in a convenient editor, not knowing html.

Plugin author says, that it is localized under dutch, French, Deutsch, Polish and Russian languages.

Externally, the Custom Post Widget plugin looks like this:
