Category Titles Visually Confusing

Perhaps I have missed this somewhere but visually when I am trying to move within my left sidebar, the Projects stand out more than the Categories. As someone who nestles categories under other categories this makes it more difficult to really move things around easily. Can these Categories be Given color options or highlighted in some way so it makes them more easily visible.

At the moment the look isn’t customizable I’m afraid, we’ll take your feedback on board, thanks for sharing.
