if there is no match on search, I need to close window one time.
First, thanks for this helpful library for me, who use sketch❤️

 my suggestion💡
when I search icon and nothing matched, I need to close window one time.😮
I want add the future when I search icon and did not match, I can go back first icons page,
by clicking kinda home button.
