On the Firewall - Rules - Interface Windows, the icon and its colour for enabled logging is hard to distinguish from the (same) icon and its colour for disabled logging - both being an 'i' in a circle, with the former being a shade of grey, the latter being a shade of dark blue.

Describe the solution you like

Make the icons and/or their colours different and more distinguishable.
