I don’t if we can name that a new feature but I think it will be a very great thing to develop a native iOS application instead of the cross-platform one.
Of course, a good idea as well to do the same thing for Android.
It will permit to avoid all the bugs linked with this way of programming.
It might help others chime in if you could list what you don’t like about the current implementation (including any bugs you feel are specific to the dev framework).
