sounds great, if whatever ends up being the default (text area) supports image uploads and the other formatting features then i will be impressed.
HTMLarea doesn't support uploads (at least not that i'm aware of - there maybe addons). My personal preference (and in no way an official position) would be to decouple file uploads from visual editing. To me these features don't belong together as file uploads are required in places that the visual editor doesn't touch (i.e non textareas).
I have, in the very early stages of development, a file upload module. This module will be available (either via hooks or apis) to all modules. So we can add upload facilites to all releveant modules via a single seccurable upload function rather than have many upload functions built into different modules and visual editors.
Users that want upload facilties can have them and those that don't need not install the upload module.
Much of this is in the planning stage at the moment but presents a more modular approach to adding this feature set to
PN.
