It would be really useful to be able to associate images and code blocks with bookmarks in various orientations. For example, taking a screenshot of a stackexchange post and being able to position that image above, left, right, or below the bookmark. Same with code blocks. This would more closely resemble aspects of Diigo and Evernote that are helpful. (They are helpful because rather than having to click the link, go to the site, and reread the forum for the answer that helped you, you can include it right there by the bookmark and save yourself lots of time).
