Adjusting the spacing with only a single icon

[rafatosta]

Currently, when limited only to 1 icon, the margin is too far away, as we can see in the image below.

Would making an adjustment be as follows?

Would it be possible to adjust the margin so that it is more harmonious with the rest of the system icons?

Thanks for the excellent work

Could the icon be replaced by an expansion arrow?
