Found by using the app the way a student does - and fixed. - A note could report "This document is empty" right after you finished writing it, and the next keystroke could make that permanent. The text was always safe on disk; now the screen tells the truth and nothing can overwrite it. - The title is a real field now: a new note opens with the cursor in the name, press Return and write. No more notes auto-named from their first line. - On iPhone, select the words that ARE the answer and tap the new card button above the keyboard - exactly those words become the hidden part. The phone used to guess. - "Study N exam cards" now opens exactly the exam session it promises, not the ordinary queue. - The AI reads your language correctly now - Russian notes with Latin medical terms are no longer misread, cards never pass through machine translation, and a correct answer is never thrown away as "wrong language". - A calm still background by default; the flashcard inside a note is a quiet card instead of loud purple fragments; the review screen turns cards with a gentle spring. - Dozens of smaller fixes across editor, calendar, search and Mac.
