The current dimensions panel has icons for padding and margin stepped controls, but not for block spacing and min-height controls. This causes misalignment of the controls, making it less scannable. Additionally, in case of width-based controls, or axial gap configuration, an icon denoting the orientation can help anchor the feature.

Here's a design proposal that adds icons for block spacing and min-height, shown before and after:

Beyond lining up vertically, this also unifies the controls so that in the future, axial controls (row-gap or column-gap vs. just gap) could be added to the block spacing control. To that end, here are potential icon designs that would work for axial gap configurations:
