+** [[https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/attachtop][Attach Top]]
+
+This is a port of attachtop patch for dwm: https://dwm.suckless.org/patches/attachtop
+
+New client attaches below the last master/on top of the stack.
+
+Behavior feels very intuitive as it doesn't disrupt existing masters no matter the amount of them, it only pushes the clients in stack down.

 Allow dwl to execute commands from autostart array in your config.h file. And when you exit dwl all processes from autostart array will be killed.
