 8 | 
 9 | - [shiftview](https://lists.suckless.org/dev/1104/7590.html)
10 | - [vanitygaps](https://dwm.suckless.org/patches/vanitygaps/)
11 | - [systray](https://dwm.suckless.org/patches/systray/)
12 | - [staticstatus](https://dwm.suckless.org/patches/staticstatus/)
13 | - [hide vacant tags](https://dwm.suckless.org/patches/hide_vacant_tags/)
14 | - [cycle layout](https://dwm.suckless.org/patches/cyclelayouts/)
15 | - [always center](https://dwm.suckless.org/patches/alwayscenter/)
16 | - [rotate stack](https://dwm.suckless.org/patches/rotatestack/)
17 | - [notify thing](https://dwm.suckless.org/patches/focusonnetactive/)
18 | - [warp](https://dwm.suckless.org/patches/warp/)
19 | - [no border](https://dwm.suckless.org/patches/noborder/)
20 | 
21 | ## Exploding Windows
22 | 
23 | With `skippy-xd` you can explode your windows and warp to whatever window you want.
24 | 
25 | ## Media keys
26 | 
27 | Here is a helpful [link](https://gist.github.com/palopezv/efd34059af6126ad970940bcc6a90f2e)
28 | 
29 | **NOTE** (I had to change "0" to "@DEFAULT_SINK@")
30 | 
31 | ## TODO
32 | 
33 | - statuscmd patch
34 | - Add sticky patch
35 | - scratchpad (maybe named scratchpad)
36 | - alternative tags
37 | - maybe steam
38 | - Add resize corner patch
39 | - Add swallow patch
40 | 
41 | ## Probably not
42 | 
43 | - pertag
44 | - awesome bar
45 | - Add alpha patch

   2 |  *
   3 |  * dynamic window manager is designed like any other X client as well. It is
   4 |  * driven through handling X events. In contrast to other X clients, a window
   5 |  * manager selects for SubstructureRedirectMask on the root window, to receive
   6 |  * events about window (dis-)appearance. Only one X connection at a time is
   7 |  * allowed to select for this event mask.
   8 |  *
   9 |  * The event handlers of dwm are organized in an array which is accessed
  10 |  * whenever a new event has been fetched. This allows event dispatching
  11 |  * in O(1) time.
  12 |  *
  13 |  * Each child of the root window is called a client, except windows which have
  14 |  * set the override_redirect flag. Clients are organized in a linked client
  15 |  * list on each monitor, the focus history is remembered through a stack list
  16 |  * on each monitor. Each client contains a bit array to indicate the tags of a
  17 |  * client.
  18 |  *
  19 |  * Keys and tagging rules are organized as arrays and defined in config.h.
  20 |  *
  21 |  * To understand everything else, start reading main().
