+# centeredmaster
+
+`centeredmaster` layout patch makes the nmaster area centered
+on screen, using `mfact * monitor width & height`, over an
+horizontally tiled `stack` area, pretty much like
+a "scratchpad".
+
+I find it useful on large screens (say 1920px wide), where
+`monocle` or `htile` feels either too large or makes me type in
+a corner of the screen.
+
+With `centeredmaster`, for instance, I can set my editor in the
+center, while keeping an eye on what's happening in the windows
+behind (logs, tests, ...).
+
+
+
+```
+With one client in master:
