Bettermark

A smarter 'Add Bookmark' buttonA better 'Add Bookmark' button. When you press the Bettermark button, the extension will attempt to add the bookmark in the correct folder in your "Other bookmarks" folder. It does this by examining existing folder names and the content of previously bookmarked sites in those folders and comparing them to the page to be saved. The implementation uses some simple heuristics along with a naive bayes classifier to try to categorize the page. If no match can be found, the bookmark is added to a folder called "Uncategorized". The extension also provides the following convenience features:

A button to add bookmark to the last folder used.
Easily create a new folder and place the bookmark in the folder.

Permissions:
This extension will need access to the tabs to look at the current page, local storage (to cache the classifier) , and the bookmark api (to examine existing folders when categorizing).
