+Subject: [PATCH] MoveStack patch
+
+This plugin allows you to move clients around in the stack and swap them 
+with the master. It emulates the behavior off mod+shift+j and mod+shift+k 
+in Xmonad. movestack(+1) will swap the client with the current focus with 
+the next client. movestack(-1) will swap the client with the current focus 
+with the previous client.

+Subject: [PATCH] Multiple scratchpads
+
+This patch enables multiple scratchpads, each with one asigned window.
+This enables the same scratchpad workflow that you have in i3.
+
+Scratchpads are implemented as special tags, whose mask does not
+apply to new spawned windows. To assign a window to a scratchpad you
+have to set up a rule, as you do with regular tags.
+
+Windows tagged with scratchpad tags can be set floating or not in the
+rules array. Most users would probably want them floating (i3 style),
+but having them tiled does also perfectly work and might fit better the
+DWM approach. In case they are set floating, the patch moves them to the
+center of the screen whenever they are shown. The patch can easily be
+modified to make this last feature configurable in the rules array (see
+the center patch).
+
+The togglescratch function, borrowed from the previous scratchpad patch
+and slightly modified, can be used to spawn a registered scratchpad
+process or toggle its view. This function looks for a window tagged with
+the selected scratchpad tag. If it is found its view is toggled. If it is
+not found the corresponding registered command is spawned. The
+config.def.h shows three examples of its use to spawn a terminal in the
+first scratchpad tag, a second terminal running ranger on the second
+scratchpad tag and the keepassxc application to manage passwords on a
+third scratchpad tag.
+
+If you prefer to spawn your scratchpad applications from the startup
+script, you might opt for binding keys to toggleview instead, as
+scratchpads are just special tags (you may even extend the TAGKEYS macro
+to generalize the key bindings).
