Launch an app in a Floating Window

Most X11 applications support a flag --class to specify the class under which the application runs. Regolith is configured such that apps with a class of floating_window will launch with i3’s floating window mode.

Examples

gnome-terminal

Launch the terminal in floating mode:

$ gnome-terminal --class=floating_window

Firefox

Launch Firefox in floating mode:

$ firefox --class=floating_window
