When a page is created (maybe other pieces of content as well), being able to add a Nav point at the same time that you're creating a page would be convenient and could streamline the process for us when developing sites.

Though I have never used this, I believe from everything I have read on it, that it would be a major upgrade over TinyMCE and fckEditor. I believe the admin speed would also increase as the total weight of the editor is only 45kb. The features I would like to personally see implemented as a part of this:

Ability to customize what controls are presented when an editor is loaded. Example: most of the time, I don't want me clients to have the ability to change font color, change font sizes, adjust justification, etc. I want them to have RTE for bold, italic, adding images, links, and adjust between headers/paragraphs/blockquotes. I believe adding this, with setting up site-wide settings and allowing overrides (for app RTE attributes, page content layouts, etc.).

This would also allow click-to-edit ability: http://imperavi.com/redactor/examples/click-to-edit/ or even the air mode: http://imperavi.com/redactor/examples/air/

It also has built in auto save functionality and supports HTML5.

Finally, this works iOS and Android 4 so editing the site on tablets and phones would be possible.

Using this would go beyond just being able to push updates (which would be nice as well).

Basically, the ability to connect to your fan page and post status (whether alone or based on content creation in Aptuitiv), creating Facebook Events when calendar events are created, photo galleries are duplicated on facebook when uploaded via the gallery, etc.

I can see a lot of cool uses for this.

There is currently no option to not use the "Main" Content Block in templates. It would be very useful to have the ability to NOT use the "Main" Content Block IF another content block is selected in its place. We have many occasions where we require one content block in a page but want to add a unique Content Layout to it which is not accessible to Content Snippets or other Content Blocks

Add ability to add microdata attributes to elements. Like the Insert / Edit Attributes pop-up. Don't want to have to edit the HTML all the time.

Using the size contraints setup when creating image attributes, it would be great to allow clients to actually be able to resize normal dimension images directly in the software, rather than requiring them to have access to some sort of image editing software.

Basic croping could be enabled by default if no dimensions are given, but if height/width constraints are added, aspect ratio and maxSize settings come into play

Ideally, font-family: Menlo, monospace;

It's easier for those using these editors to read monospace code.

We need to have the ability to add an Alt Tag to images in an Image Set, like you can in an Image Upload field. Currently there is no way to add an Alt Tag so it is badly affecting SEO.
