Hey Alton,
you’re right – I’ve discontinued IE8 support in Kanso and other items of mine because this browser represents a small and quickly diminishing fraction of the total internet usage (3.1% as of January 2014); ThemeForest made IE8 support optional as of November 2013.
Should you have additional questions about the theme, do not hesitate to contact me!
Sincerely,
Andrii / Satori Studio
