Firefox/Feature Brainstorming:Notes and Annotations

Annotations

Ability to right-click "Add sticky note" on a webpage and have that note saved and displayed every time I visit that page. Naturally, I should be able to make stickies whatever colour I want, and format them as Rich-text with fonts and so forth.
Sticky manager that lets me search/browse through all my stickies by date/time, location, tag(s), keywords, full content, etc.
If the Sticky system could auto-link stickies together using a simple wiki-like markup system, that would also be cool. Sort of a personal wiki overlay on the web.
Need to be able to tag sticky notes

Ability to click-drag an area of a webpage and "clip" it to be saved in a scrapbook/notetaking feature. Sort of like tearing a piece out of a newspaper or magazine. Doesn't have to be any more complicated than simply taking a screenshot of that area in the browser or somesuch, and allowing the user to drag/save it in a notebook.
Need to be able to tag clippings

Some system where users can make notes, drag clippings, organize or reference sticky notes, etc.
Need to be able to tag notebook/scrapbook pages

Allow annotations of any link on any web page displayed in the browser.
Disable display or function of any link to a page that is dead or garbage.
Have the annotations specific to what you are looking for during this session.
Invert a page of links (like those from a search engine), and have the page links displayed according to the annotations you've made.
