Elastic textarea height and fixed toolbar for wp-admin editor

[antitoxic]

The fixed toolbar I'm thinking of will be fixed to the top of the screen whenever the page is scrolled as much as to hide it. Like the gmail toolbar.
The usability gain is clear: You can access the toolbar at any point of editing the post

The elastic textarea will be useful in writing long articles but still having quick access to the translation tabs (which appear when you have i18n enabled using third party plugins such as qTranslate)

The admin bar is already going to be fixed to top of screen with 3.3 changes.

Textareas can be dragged to be taller in modern browsers that support it.

Replying to jane:

I think antitoxic might be talking about the editor toolbar, not the admin toolbar.
