This new feature addresses what was, imho, the biggest Evernote limitation; see the link below for more details and other new features. Microsoft OneNote still has a more elaborate containment and linking model (with the ability to organize notes in and link to notebooks, section groups, and sections, as well as notes and intra-note info items), but this is a big hypertext step for Evernote.
It’s not often that a single feature has the potential to dramatically improve Evernote for all users. It may not seem like much at first, but Note Links is exactly that kind of addition. As the name suggests, Note Links are links to individual notes that can be placed almost anywhere. Create a note link by right clicking on a note and choosing the Copy Note Link option, or choose it from the Note Menu. The link is then placed into your clipboard.
You can paste that link into just about anything—other notes, calendars, to-do lists, third party apps, etc. Whenever you click on the link, it’ll open the note. If you Shift+Click (Windows) or CMD+Click (Mac), it will open the linked note in its own window. We’ve already updated the Web, iOS and Android versions of Evernote to support this feature, so if you click a note link in those environments, it’ll take you to the right place.
Note Links also work in Shared notebooks, allowing notebooks authors to guide visitors through their notebooks.
