Ask HN: App for writing notes in the margins
I am looking for an app that will allow me to read books, take notes, and reference the notes at the page I took them.  I would like to be able to do this from my computer or phone.<p>Is there an obvious app I&#x27;ve missed that will allow me to do this?  I&#x27;ve tried Evernote and Mendeley previously.  Both seemed to work for simple papers but were missing common book reading tools.<p>Thanks.
