On the iOS version is doing great and I like the features provided but in Desktop version, I still prefer the legacy Evernote.
My suggestion, I think what you need to improve are:
The "search engine" sometime I can't find my documents even with the correct key words
I think improve the search method where having a build-in A.I like what Google did in their search for new movie.
SYNC issue - e.g. sometime I notice my image disappear from the document. Prefer at least Evernote keep latest copy in your history so I can retrieve if there is any issue occurs.
For timing being ... I stay with the old one.
