To my knowledge, there is no way to adjust the spacing between fields when they are boxed.
This would be a non-issue except that spacing between fields is randomly adjusted when dragging items around and nesting them. The only way to undo this is by removing them from the boxed layout and trying again. Sometimes you can duplicate a field and then drag it into place to resolve the issue.
I imagine this is a fringe case. Ideally, I would like to be able to select the box with all items inside it and then adjust the spacing. Additionally, if spacing could be applied on a per-field basis, you could get as granular as needed for any use case.
Thanks for looking into this for me.
