Our Ultimate Sales Boost app works by automatically inserting the widgets based on the structure of the theme. Specifically, the widgets are inserted when loading the relevant template page of your theme. This approach is necessary because there are so many different Shopify themes.
Unfortunately, the use of automated insertion makes it impossible to customize the insertion location of the widgets.
The only way to either add or remove spacing would be to edit your theme's template. It is recommended to hire a developer for any theme customizations, and to implement any edits on a duplicated copy of your theme.
