Could the position and width bar perhaps have a number of currently selected value for easier of aligning subsequent ribbons with same values.
Right now it is rather annoying to squint my eyes to check the notches whenever I want ribbons with same positioning
Edit. So I used the Oak Leaf Cluster with green color and they appear as black on the actual ribbon but look just fine on the preview screen
Edit2. Looks like it's the color that is causing issues: RGB 23, 164, 45
Edit3. Looks like all green colors turn a lot darker on the actual ribbon. Maybe green color is not being transferred properly?
