Request: Sunpaper

Project information: A Linux utility to change wallpaper based on local sunrise and sunset times.

It works with several modified dynamic themes to move through eight images depending on the position of the sun at your location and time of year.

Compatible with any distribution and window manager (X or wayland).

Name: Sunpaper
License: Unknown (open source)
Upstream has been contacted: No

As upstream suggest, it is better for Sunpaper to be distribute from the Linux distro rather than Flatpak.
