So the iOS app has a dropdown menu for mnemonics and that's great, but how hard would it be to add another button to the left or right of that one for example sentences? I'm dying without some example sentences to help me remember.

Thanks for a great app and looking forward to some updates.

I believe the guys have said they'll add example sentences to the app after they have overhauled the example sentence system, which is high on their to do list, just below app-related stuff. So hopefully it will happen soon; I'm also looking forward to this.

I don't know if you have Pleco, or what your level is, but I can use the "send to Pleco" function (with the character or word displayed, tap "i" in the upper right hand corner, the"Pleco" in the upper left hand corner.) The dictionary entries have sample sentences. TL (Tuttle Learner) dictionary of Pleco is good for less advanced learners.
