My students have not found the accent keyboard to be very user friendly and has caused considerable stress during testing situations. Perhaps modeling it after how conjuguemos.com does it would be a nice option. For instance, when a student presses a letter that has other options, for instance u, they are then the options of ú and ü appear.
Hi Michael, we really only recomment the language keyboard for less commonly taught languages. For other languages, both PC and Apple devices have made it very easy to type with accent marks which is what we would recommend for the time being.
Thank you for the example with conjuguemos.com. This is something we can keep in mind in the future.
