MacBook Pro Trackpad Handwriting

Prior to macOS Mojave, the trackpad handwriting would never stick around for long.  It simply disappears after sleep or whenever it decides to disappear.

I have the macOS Mojave installed for two weeks and the trackpad handwriting still sits neatly on the there so in my book Mojave is a great success, it finally fixes something not a lot of people care.  I mean the fix could be incidental but hey I will take it.  Before Mojave I have seen a few threads mentioning about this annoyance on the Apple discussion forums but there aren't really
any real solution to it.  Trackpad Handwriting isn't exactly great great but I like to have that option always sitting there when I want to use it.  I prefer to use the iOS handwriting.
