訳:She reserves a table.
Using the future tense certainly isn't incorrect. However, right now our priority is getting all the wrinkles ironed out so that we can get the course out of beta. We have to put in possible translations for each sentence by hand, and there are thousands of sentences. Given that our team is small and other tasks have taken priority, we haven't been able to add future tense versions of many sentences yet. Hopefully we can address this in the near future, but in the meantime, we appreciate your patience!
