I haven’t found a way to reject a hint in such a way that it no longer appears on the archived hints list. If a hint is not a match there is no need to see it again (although RF might want to keep track of the fact it has been looked at an rejected so it isn’t offered again). If a hint is a match, then having a way to recognise this (eg a tick box) and keeping a record of that in the ‘accepted hints’ archive would be useful. Also there is opportunity to add notes to the text and that is useful.
Perhaps I’m missing something here, but some hints are far from a suitable match and only clutter up the archive record.
