The only reason why I still use Anki on desktop is for its ‘find and replace all’ function. I would appreciate it if I could do this on mobile too.
That is, a function that allows you to enter a query and replace all occurrences with something else,
- in all selected cards/notes, or all that match some search query, or just your entire collection;
- optionally using regex, including capturing groups: \1, \2, …
It would be useful for maintaining huge decks of cards.
