DISCONTINUED:
As I no longer have the LG V20, I can't properly develop this app. The source is available on GitHub and linked below, if anyone wants to fork and improve it.

Ever wish that LG had given the V10/V20 more widgets in the second screen? Well, wish no more! BoredSigns adds many more widgets to your SignBoard (get it? SignBoard --> BoredSigns?), ones you may need and ones you may not.

The best part about BoredSigns? It doesn't need root! That's right; you can get some brand new widgets on your completely Stock V10 or V20. In the future, ADB may be necessary for certain widgets, but right now, you don't need your computer at all.

You can even select which widgets will appear in the AOD!
There are, however, a few problems with this.
1. The AOD only updates about once every three minutes
2. The AOD will scroll back to the default screen automatically after a while. This can only be changed with root.

Current widgets:
— Information
— Current Weather
— Forecast Weather
— Image
— Navigation Bar
— Developer Info
— CPU Info

If you're on a rooted V20 and looking for additional functionality, consider installing my mods: https://forum.xda-developers.com/v20/themes/mod-aosp-signal-bars-t3551350

This app is open source! If you aren't willing to pay $0.99 to buy it, feel free to build it for yourself. I only ask that it not be re-distributed without substantial modifications (i.e. more than changing the theme and name).
