+ * We will see both launcher and wallpaper in that list.
+ * Once the interaction with a particular set of connections starts, no new logs will be printed

+ *
+ * The following items are skipped, to reduce the logspam:
+ * ACTION_OUTSIDE: any windows that are receiving ACTION_OUTSIDE are not logged
+ * ACTION_UP: any windows that receive ACTION_UP are not logged (for both keys and motions).
+ * This includes situations like the soft BACK button key. When the user releases (lifts up the
+ * finger) the back button, then navigation bar will inject KEYCODE_BACK with ACTION_UP.
+ * Both of those ACTION_UP events would not be logged
+ * Monitors (both gesture and global): any gesture monitors or global monitors receiving events
+ * will not be logged. This is omitted to reduce the amount of data printed.
+ * If you see <none>, it's likely that one of the gesture monitors pilfered the event, and therefore
