As said in another thread:
Right now I’m working on a Nitrogen replacement capable of working on Sway. But this should be discussed on another thread.
Azote is a GTK+ 3-based picture browser and a wallpaper setter, which works as a frontend to swaybg (Sway) and feh (X11).
Since the most commonly used desktop background browser and setter is aimed at X windows, and doesn’t work on Sway, I thought to give
swaybg command some user-friendly GUI. In order not to limit the program usage to Sway only, Azote is also capable of using
feh, when running on i3, Openbox or other X11 window managers.
