Enable the full toolbar on flashcards
Allow users to use the same tools as on regular pages: highlighting in color, underlining, bold text, and free writing/drawing. This would make it much easier to emphasize important content and quickly add notes or markings.

Support combined text and images on a single flashcard
Make it possible to place both images and text together on one flashcard for better visual learning and more flexible study methods.

Detect and indicate duplicate flashcards:
Show a clear warning or indicator when a flashcard is created twice, to avoid unnecessary duplicates and keep decks organized.
