I just wanted to show off a cool project I've found recently. Dashy is a very customizable dashboard that works perfectly for self-hosting projects. You can monitor any service that is reachable via http/https and use widgets like the universal web search interface, I've enabled in my installation.

I only use it as a glorified startup page for my browsers with the search function, but to give you an idea of what's possible, you can take a look at some more creative examples as well.
