+## Motivation:
+
+The goal is to further support touch-only usage of the BangleJS 2 watch. You can use the [Swiper Clock Launch](https://banglejs.com/apps/#swiper%20clock%20launch) or the [Pattern Launcher](https://banglejs.com/apps/#pattern%20launcher) to further enable touch-only support of the watch.

+ * How does this work?
+ * 
+ * Every *boot.js file is executed everytime any app is loaded, including this one.
+ * We just need to figure out which app is currently loaded, in case we are in the white list / black list mode,
+ * to figure out if the swipe handler should be attached or not.
+ * It does not seem to be the case that this can be done easily, but we can work around it.
+ * It seems that every app is loaded via the global "load" function, which takes a fileName as it's first parameter to load any app
+ * or the default clock when the fileName is undefined.
+ * To be able to use this for us, we wrap the global "load" function, and determine before loading the next app,
+ * whether the swipe handler should be added or not, since we now know which app will be loaded.
+ * Note: We cannot add the swipe handler inside the wrapped "load" function, because once the "load" function is complete
+ * everything is cleaned up. That's why we merely save a flag, whether the swipe handler should be attached or not,
+ * which is evaluated once this file is executed again, which will be right after the load function completes
+ * (since every *boot.js file is executed everytime any app is loaded).
