+namedscratchpads
+==========
+
+Description
+-----------
+Allows for the creation of multiple scratchpad windows, each assigned to different keybinds.
+
+On pressing the keybind the window will either:
+* Spawn based on the given command, if it's not already running
+* Toggle visibility of the window
+
+A new field in the rules array is added to associate the command with the corresponding rule.
+
+Works well with [floatrules](../floatrules/) for window positioning.
