Localize copies a set to another source language with the translations emptied — what carries over, what does not, and why the taught language cannot change.

Paste up to 50 words at once, choose the separators, and mark the practised word in every example with double parentheses so exercises can find it.

A word card crops every picture to 3:2 from the centre — the sizes that survive that crop, the formats it accepts and the ten-megabyte limit.

A set is private until you say otherwise — what a link and the public level really grant, and why an assigned task gives a student no access to the set.

Removing a language pair hides everything that was created inside it. Nothing is deleted — add the pair back and it all returns.
