The web is a powerful thing, with the right capabilities you can create tools and services that can be deployed without a central authority and can also deeply integrate with the peoples devices. I love being able to tinker and scratch an itch quickly. The itch in question was that I'm a heavy user of .new domains and I wanted a quick way to have access to them on my Android home screen so that I can start a task without having to find the app, go through its menus and then create the "new" thing.
I thought this was rather cool and I discovered it by accident, but it looks like Twitter implemented shortcuts. It's great to see web sites and web apps being able to do things that users expect installed applications to be able to do.
I love view-source, it's a nifty super power of the web that nearly all mobile browsers are trying to kill. Not exactly sure why. View-source is what got me into web development because I could see how other people structured their pages, and at the time I started web development it was pretty much the only way to debug web pages. I've also been using my iPad Pro whilst I am not at work for the next month or so.
