+** [[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.

 ** [[https://codeberg.org/dwl/dwl-patches/src/branch/main/patches/autostart][Auto Start]]
 
 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.
