Question: The touch icon files used in Safari are stored on a mac in the folder ~/Library/Safari/Touch Icons, and each file in a .png file, with what seems to be an arbitrary name.

By swapping an image in this folder, I can change the image displayed in Safari in the bookmarks bar. However, I can't do the same for the bookmarks without an image already in the folder.

Does anyone know how Safari names these files, and how it connects a bookmark to this image?

Answer: 
As of watchOS 4, you have a few options for accessing the Now Playing screen:

* Set the Dock Ordering setting for the Dock (Watch App on iPhone > Dock) to **Favorites** and choose the Now Playing "app" as one of your Favorites
* Add the Now Playing complication to a watch face (unfortunately, it's only available for Complication sections that are big enough to show the title of what's playing)

I actually included this in a roundup of [things I think should work with Siri on the Apple Watch but don't](https://medium.com/@gohnjanotis/siri-stuff-that-should-work-on-watchos-but-doesnt-476fbedd7fb0).
Update the wake screen setting to show the last used app.

Go to General > Wake Screen > On Screen Wake show Last app on the iPhone App.

You can choose from options include session, 8 minute, 1 hour, always.

Now the watch always wakes up to the now playing screen.
