Rafael, great to see that even in Evernote forums there are rude real world people <sarcasm off>. I was just looking for an older software that could be used for visual exploration of my Evernote data, when I found your request that I support. I have often used the Bubble Browser to discover new topics in my EN notes – that couldn't be done with the standard view. And there is still the download site at Evernote (https://appcenter.evernote.com/app/bubble-browser/mac/index.html). Unfortunately the software isn't updated anymore – I wish EN would support this. And yes, I like the Zettelkasten approach, too.
P.S. Never trust people who quote Goethe.
