Another old request, I did not even realize the original post date until I scroll down to see other comments!
I voted it up.
One of my issues is the ability to connect notes and make connections on the fly. For example, you are in a note and you want to reference a different note in it, I would find the other note, copy the link, go back to the original note and paste it.
When you have a lot of notes, there could be many connections and links and that is part of Evernote's strength (for me) to be able to make connections between your ideas, notes, projects, tasks etc.
In short, I would love to be able to create a note from a highlighted text inside a note. This will lead to more brainstorming and jumping from one idea to another and let the flow going but also be able to trace back ideas.
In summary, I would love more connections (ability to create connections in a faster, easier way, for example, scrolling all your notes within the note to paste a link) within Evernote.
