Take the most basic functionality of Roam Research and add it to Evernote and you have the perfect product.
At it's most basic you want to be able to search other notes from within a note and link to them.
Be able to create a note with a certain name from within another note if it doesn't exist.
Either have the option or have it automatically happen that any note linked to shows an automatic backlink each note linked to it
This would be much more complicated but if you could link to a block / anchor within notes that's a bonus
REALLY NICE TO HAVE BUT NOT KEY TO THE ABO
