I’ve noticed that if you study for exactly one hour, you’re told “Studied n cards in 1 hours today (_m_s/card).”
This is an incredibly minor point, but ideally it would say “1 hour” instead of “1 hours” (but be plural again for “1.1 hours”, “1.2 hours”, etc.).
There would be problems when translating into other languages that have considerably more complicated numbering grammar beyond the simple “1=singular, other=plural”. Slavic languages, for instances.
Perhaps a grammar-neutral version, like:
Studied today:
Cards: n, Hours: 1
Our code can handle such plurals already; this is a corner case. I’ve logged it on “1 hours today” · Issue #3102 · ankitects/anki · GitHub
This is an excellent point.
