+# Replicate some of Awesome's default layout manipulation configuration for Sway
+#
+# Differences:
+# - Layout switching doesn't use the spacebar (i.e. i3/Sway behavior to switch to/from floating windows)
+# and uses the 'A' key instead (as in auto)
+# - Resizing windows uses i3/Sway's more versatile Mod4+r
+# - no tags
+# - no Maximize/Minize, alternatives to Maximize would be to switch to Stacked/Tabbed layouts
+# via Mod4+w or Mod4+s.
+# - kill focused client is available on Mod4+Shift+q (instead of Mod4+Shift+c, which maps to Sway's
+# config reload)
+# - probably many more ...
