On the result page of a word question, there is an example sentence at the bottom, which can be extended to a list. Currently for the list there are the following options under Settings -> Sentences -> Order sentences by:
Normal order
Shortest
With audio
Most liked
Currently, the example sentence seems to always be the same sentence for the same word, and the list is always in the same order, depending on the setting, so all the order options are deterministic.
E.g. for 会, the example sentence is always 彼はその会に社長の代理で出席した, which is the first entry for the list in the dictionary entry for 会. However, there are a total of 132 example sentences for this term, so for variety, it would be nice to have some kind of randomization options, e.g.
Random order
Random order (prefer audio)
Or, if fully randomizing the sentence order is too complicated, maybe it could be possible to just pick a single random example sentence, but leave the list as it is.
