Hey Rhodesman,
first of all, thank you for the purchase!
The possibility to add external links to the one-page mode was not initially conceived for Kanso, yet following user requests I’ve decided to implement it – it will be a part of the version 1.5 that I will make public very soon. Meanwhile, I’ve already uploaded the necessary files to add this feature in another topic here – please see the first two messages for details. Let me know if the provided solution works for you!
Sincerely,
Andrii / Satori Studio
