Official Lithuanian keyboard standard has letters ĄČĘĖĮŠŲŪŽ on the number row for quick access. While numbers can be accessed by long pressing LT letters, because we use LT letters much more often (almost in every word) compared to numbers.
Current Swiftkey Lithuanian layout has LT letters accessible only by long pressing (to get ą we need to long press a). And this is painfully slow to type.
