Not Enough
Most language studing app(ex: Tedict, Speater, etc.) does not support Split View so when this dictionary app locates in an non-fixed Split View, the Problem is that Bluetooth keyboard does not work for this dictionary app in the non-fixed Split View. This is very irritating. How about that THIS APP GO INTO THE POP-UP NEXT TO "PASTE","SELECT" WHEN A WORD IS PUSHED LITTLE BIT LONG TIME?
