Is there a sane WYWIWYG editor based on contentEditable?

Question

JavaScript

Actually, there was an urgent need for a flexible and simple editor (flexibility is expressed in the design settings through CSS, at least, and more decent panel layout, so that it can also be slightly tweaked through CSS).
I'm currently in the process of writing my own editor that would fit perfectly, but the reality is that I don't have two weeks to finish it. Therefore, a ready-made editor is of interest.

From the requirements, the contentEditable is inside the div and not the iframe, in order for it to stretch depending on the content. Alas, of these I know only NicEditor, but it is obsolete. In fact, I am currently rewriting it.
Another requirement is IE7 support. That narrows the circle of editors.

Of the functionality, you only need text formatting, nothing overly complicated.

If the editor is implemented on jQuery-like libraries, it is even better.

Answer 1

Maybe this redactorjs.com/ is for you? jQuery-plugin, without using iframe'a, drags on.
The only thing is IE8+.

Answer 2

Inline not only NicEditor but also:
Aloha Editor
FresherEditor (here just with JQ)
