I'm a long time and a huge user of Evernote.
Since the rewrite it has been a nightmare. Yes as it's already said : it's so slow. But not only : UI events are handled in random order, with keystokes handled before mouse clicks, even if you did it the other way. The worse thing I've ever seen in decades of computer usage.
The longer the notes are, the worse it is. And some of my notes are really long. It's unbearable.
The rythm of new versions is intense, and each time I hope a performance improvment, but no. More features I absolutely don't care about.
There are UI changes that disn't make sense to me, the legacy version was absolutely OK. But the performance problem is so huge, it makes everything else minor or irrelevant.
Please, no more features or "improvements" until the performance problem is solved. It deserves each and every development capacity you have. Please !
