Took a look at this and thought about spacing/touch targets on our smallest screen size (320px)
If we use the full width of the post we can increase the touch area of all icons and expose an additional one for non-admins… we can also put more space between the icons, which allows us to more closely associate the like count with the heart.
Current controls on the left, adjusted on the right
For admins, we can keep the icons the same size and fit it all one one line as long as we shrink long like counts
