Sadly I have to agree - I love(d) EN and use it all day every day for everything. For now, I'm clinging on to the old version but will have to cancel membership & look for something else (argh!)
v10 is on so many fronts is a retrograde step giant leap off a cliff
Basic core OS functionality has gone (intuitive stuff like shortcuts, renaming or dragging Notebooks)
It's slower (!) and sucks system resource
Sync missing
Note formatting that looked fine on v6 has gone to ***** in v10 - reformat all your notes anyone?
Can't present
etc etc etc
Sad.
