+## Limitations
+
+* **Mutli-Monitor**: I don't have a multi-monitor setup at home. Most likely it won't work properly. Pull requests are welcome.
+* **Copy**: Copy to clipboard won't work if you close swappy (the content of the clipboard is lost). This because GTK 3.24 [has not implemented persistent storage](https://gitlab.gnome.org/GNOME/gtk/blob/3.24.13/gdk/wayland/gdkdisplay-wayland.c#L857). We need to do it on the [Wayland level](https://github.com/swaywm/wlr-protocols/blob/master/unstable/wlr-data-control-unstable-v1.xml), or wait for GTK 4.
