In 3ds Max spinners are incremented by different amount depending on what values they adjust, for example size spinners are incremented by 1%, randomization seed spinners are incremented by 1 digit, other spinners are incremented by 0,1 digit. Corona on the other hand adopted only one way to increment spinners - by 1% which is not always optimal, for example when you want to increase/decrease randomization seed in Corona material, it will advance by 1 between 0 and 150, by 2 digits between 150 and 250 and so on, which feels inconsistent and pretty confusing. Please consider to improve this behaviour. Thanks.
