It is glad to see that theme development is much faster now than past. Albatross theme is forked from Shimmer project team, they stopped the development long ago. If you want to keep your desktop simple, clean and elegant then for sure this theme is for you, it is specially targeting Gnome desktop and may work with Xfce. Currently this theme is compatible with Gtk 3.24+/3.22/3.20. If you intend to use this theme in the Xfce desktop then you must use xfwm4 from “Greybird/Adwaita” since that is not packed with this theme. Since this theme is in active development, if you encounter any bug or problem with this theme then report it to get it fixed. Obsidian-1 icons used in the following screenshot.
