+Several [i3](https://i3wm.org/) features [remain to be implemented](https://github.com/SirCmpwn/sway/issues/2).
+
+* Runs natively on [Wayland](https://wayland.freedesktop.org/) (duh)
+* You can use your `floating_modifier` to resize and move tiled windows
+* Sway includes the features of the i3-gaps patches
+* Sway handles things like output configuration (rather than something like xrandr)
+* Sway supports multiple non-modifier keys when assigning key bindings
+* The default keybindings in sway are different from those in i3. Read your sway config to learn them, or copy over your i3 config to use what you're used to.
+* Sway handles your wallpaper
+* Sway handles input configuration (man sway-input)
+* Sway is documented through man pages, rather than the website
+* A few i3 commands only make sense on X11 and aren't present in sway
+* You may occasionally run into minor inconsistencies between sway syntax and i3 syntax. Just tweak your commands to be a bit more explicit if necessary
+* i3lock forks into the background when run. For swaylock, this behavior has to be explicitly requested via `-f`
