I have been using Diigo for bookmarks and highlights, Evernote for documents and image files. Both of these services offer program search results inside of my google search results. This allows me to use the google search for an "all in one", getting any bookmarks, highlights or notes found between the other services to all be shown on one page along side google results.
Is there any feature/add on that can return my search results on google search page like the options I use now? I find those to be SO helpful and the only lacking feature for me to make the switch.
