Here's what I remember:
* Media db: I already discussed this to some extent with Garvin. Bottom line is, the current media db is not ideal. We might want to replace it altogether (which could be hard due to licensing) or give it a serious rewrite (which I can't do on my own). I have, however, rewritten most of the media db to sensible HTML markup, so we wouldn't necessarily have to start from scratch.
* Navigation: I'm still not sure whether the current structure of the navigation is the best we can do. I have some ideas in my head which would also influence the possibilities in terms of styling it, but there's no clear vision of it yet. It could also be an issue with plugins which create their own navigation items like the static page or freetag plugin.
* “Reduced” backend: I still think it's a good idea to have certain areas of the backend emit or display a “basic” version of the interface which can be extended to an “advanced” backend, i.e. showing/hiding the more advanced options of certain pages. I think we need to discuss this further, though.
* Javascript: If we want the backend to be as flexible and accessible as possible (I think we should want that), it should work without JS enabled, at least its core functions (which I think is possible). Also, we do want to rewrite the JS parts to make use of jQuery. If we agree on both, it might actually be a good idea to strip all JS from the backend for the time being. That would make it easier for me to develop the markup and styling as well as to test the JS-less backend.
* Inline JS/CSS: There are some parts of the current inline JS/CSS which use Smarty variables (which is not possible in external JS/CSS). We could store these Smarty variables in elements accessible via the DOM (i.e. hidden inputs with an id), but I'm not sure whether that's actually a smart idea.
I think that's about it.
