“Grade Now…” functionality

> The recently added “Grade Now” feature on the Desktop doesn’t seem to have made it into AnkiMobile.
>
> Tap on the magnifying glass icon
> Tap on any line in the search listing
> Tap on Tools at the top of the screen
> The menu has eight items including “Set Due Date”, but no “Grade Now”
> There doesn’t seem to be any way to customize the Tools menu either
>
> I use desktop Anki almost exclusively, and AnkiMobile hardly ever, so this isn’t a personal priority. However I do use Grade Now very often.
