Long time user of the Evernote product on multiple platforms. Apologies if I am breaking rules etc, but wanted to put a suggestion out there regarding note links.
One of the essential features of our brains (which is an often used metaphor for Evernote as an external brain) is the way connections are made between pieces of information -> i.e. links between notes. The current desktop clients allow this to be achieved by finding a related note (manually using search or browse), right clicking and copying the note link, which can then be pasted into the current note. This could be vastly improved (in my opinion) by implementing something similar to Quip using the '@' symbol, and then typing the first few letters of the note title you want to link to (see pics below).
This implementation (in Quip) works on the iOS client apps as well.
As someone with thousands of notes that form a bit of a working knowledge base, this would be a welcome addition as interlinking information is a key part of learning and consolidating.
