Contrasting color for slider bar at the bottom of the worksheets
My worksheet comes in too wide to easily view; have to adjust the visible portion using the slider bar at the bottom of the screen. However, that's about the same color as the background-makes it harder to grab the "active section". Suggest you make the active section (that you need to select w/mouse) a contrast color so it stands out better.
I would also like to change the color of each sheet. So this is a good suggestion.
