Alternate Layout Groups with float-based padding?

As I’m building world-space UI for my game I’m finding it quite limiting to work with the builtin Vertical/Horizontal Layout Group and its padding being restricted to integers rather than floats.

I wonder if there are any alternatives to these, or in general more flexible/powerful layout options for smaller (world-space GUIs) where 1 unit is just far too huge. I’ve already spent quite a bit of time browsing the asset store, but can’t really find much useful stuff.

The only workaround I found is to work in a more fine-grained resolution and then apply a scaling to the World Space Canvas.

Like if you want a padding of 0.1 meter, work in a scaled up version with padding = 1 and then scale it down.

This worked for me just fine, thank you!
