Hey Björn,
there is currently no back-end option to change the spacing between the sections of the one-page layout, yet you can use some custom CSS to achieve this – please go to the “Style: Add Custom CSS” tab of the Theme Options panel and add this code, then click “Save All Changes”:
.page-template-page_one-page-php .page-holder {
padding-bottom: 60px !important;
}
You can use any other figure instead of “60” to adjust the spacing according to your needs.
Sincerely,
Andrii / Satori Studio
