The main thing preventing myself and other developers I know from using Evernote is the lack of support for syntax highlighting. The developer community is a large target market, and worth the cost of implementing this feature. I am aware that there are some third party tools that help accomplish this, but from what I have seen, they are not very good. What's interesting (observation, not a criticism), is there is syntax highlighting built into this forum editor but not the Evernote product.
Forum Syntax Highlighting:
const hello = 'there'
Product Code Block but no syntax highlighting:
This sounds trivial, but is the only reason I have heard why developers do not use Evernote. If I were the developer implementing this, I would estimate one week to implement and test this feature.
Here are about 25 ways to accomplish this either for free or in a cost effective manner: https://webdesign.tutsplus.com/articles/25-syntax-highlighters-tried-and-tested--cms-23931
