I am a Korean user using WHIMSCAL.
As far as I know, not many Koreans are using WHIMSICAL yet, but there are a lot of things that are a little lacking to use in Korean.
In particular, when using the input components and notes provided by default in WHISICAL, Korean may not be recognized properly or displayed strangely.
I think it would be good for Koreans to do business, but it is difficult to introduce it to others because Korean language support is not normal.
You must be very busy, but we would like to request a review of Korean language support.
