[Sage] Can Sage work with the extension "del.icio.us" ?

[Xu Zhe]

The extension  https://addons.mozilla.org/firefox/3615/  is "del.icio.us 
Bookmarks" that it replace the local bookmark and use online bookmark.
   It is wonderful and I like it. But after I installed Sage, I found 
that I can not edit the feed list because it use the local bookmark.
   So, can you make a little upgrade to make Sage use a profile to store 
feed url?
