This module aims to implement optimized CSS delivery by inlining stylesheets which are critical for rendering 'above the fold' content and load the rest asynchronously via JavaScript.
This module will generate pre-rendered preview for each text_format field directly below it. Rendering is based in two factors - text value and text format.
DO I NEED IT?
At some point i was tired of creating custom pages using menu and form api, writing tons of code just to have a page with ugly form where client can enter some settings, and as soon as client wants to add some interactions to the page (drag&drop, ajax etc) things starts to get hairy. Same story was with creation of dedicated CT just to theme a single page (like homepage) and explaining why you can only have 1 node of this type, or force it programmatically.
If this sounds familiar, then this module may be just a thing you were looking for :)
