The preview shows why I might have kept the padding at 1rem - the Project XYZ title is at data-depth="0" which only has padding-left: 1rem so it is left-offset from other items.

Hi folks, just wanted to update that this PR is still on my radar and will hopefully look into it this week.

@recrwplay this PR is quite old now - are there improvements here still worth adding?

@davidoliverSP2 Now even older... I think we can close this one.
