1. Video

Clients always want to embed video into their websites.
2. Clips

This is something the old editor did support but never was activated on BC.
This would solve a lot of in content formatting limitations BC currently has.
Clips could be something specified in the partner portal tools or a series of .tpl files. This looks straight forward to install but would allow some great snippets to be created and allow clients to use them and not have to format things so much. These would include custom separators, highlighted content, styled tables etc.
3. Partner access to editor?
With the API support and plugin abilty of the editor, maybe you could give partners access via the partner portal to allow us to put in some of the things we may want to add to the editor?
4. Colour Picker Option in Colour choices
5. Subscript, Superscript options
6. Misc:
redactor-plugins/clean_text.js at master · johnsardine/redactor-plugins · GitHub
Clean text option
Why? Restores some functionality like the old one. This editor handles word content etc better by a mile then the other editor but someone may want to clean up content.
Multiple file upload support:
At the moment you can only upload one file at a time.
Spell Checker - http://jquery-spellchecker.badsyntax.co/redactor.html
Why? People may want to spell check. This is not a major but nice to have
Insert Link Modal - Include Mailto Support (with class ability too)
Why? - People need to insert email links on their site.
Support 3rd Party file hosts for file hosting/uploading:
I have seen Amazon S3 and Dropbox and Google drive support to upload files from these sources
