Years ago, I've moded Tomato firmware just so I could get a better-looking router firmware management GUI. It ended up being a whole big project. So now years when I finally live in my own home, I bought a rack and 4U server which is basically a hypervisor that also runs FreeBSD-based Firewall called OPNSense. I have to say I love OPNSense. I love the interface and everything around it. However, the colours and padding's were a little off to my eyes. Because OPNsense is easy to mod, I've decided to create my own theme based on the original Advanced Tomato Project.
