Could be that I was a bit 'slippery' in the iPad app (I don't use the app on the iPad very often) but I find it hard to believe I could have moved all notes to the trash without noticing. Also, I really recall the notes being gone the second I opened EN, without me even 'clicking' or tapping anything. Another thing: the last time before 'the disappearance' I used EN (or synced to it) was when I saved an article to EN with the web clipper (Chrome). I don't remember if this note was still 'present' when I opened the iPad app, it might have been the only note not in the trash folder but I'm not sure. On my macbook pro, there's no actual delete key and I think I use cmd+backspace to move stuff to the trash in most apps so accidentally pushing two keys at once is tricky. EDIT: I just tried only clicking backspace in EN and it deleted the note, so this is different from how I normally delete stuff on my mac (in 'native' apps at least). Not asking for confirmation (or the 'regular' two key delete-thing) is a bit 'risky' but then it would still be just one note (or perhaps a few you have selected all together); this happened to all notes across multiple notebooks so that is especially weird. Another improvement for this would be to not let the Trash folder be in the notebook pile, it doesn't really stand out this way. I think when I opened EN on a different platform (can't remember if I checked web first or desktop first), I did see the amount of notes in each notebook, and then when it synced, they had all 'disappeared'. I'll just keep using EN for now and if it happens again, I'll try to be more alert about what happened exactly.
