+   * * 'clock' - called for clocks. Sets `Bangle.CLOCK=1` and allows a button to

+   *   * Bangle.js 1 BTN2 starts the launcher

+   *   * Bangle.js 1 BTN2 starts the launcher, BTN1/BTN3 call `cb(-1)` and `cb(1)`

+   *     hand side calls `cb(-1)` and `cb(1)`
+   * * `{mode:"custom", ...}` allows you to specify custom handlers for different
+   *   interactions. See below.
+   * * `undefined` removes all user interaction code
+   * While you could use setWatch/etc manually, the benefit here is that you don't
+   * end up with multiple `setWatch` instances, and the actual input method (touch,
+   * or buttons) is implemented dependent on the watch (Bangle.js 1 or 2)
+   * ```

+   *   // dir is 0 when button pressed

+   *   remove : function() {}, // optional - add a handler for when the UI should be removed (eg stop any intervals/timers here)
+   *   redraw : function() {}, // optional - add a handler to redraw the UI. Not needed but it can allow widgets/etc to provide other functionality that requires the screen to be redrawn

+   *   clock : 0 // optional - if set the behavior of 'clock' mode is added (does not override btn if defined)
+   * });
+   * ```
+   * If `remove` is specified, `Bangle.showLauncher`, `Bangle.showClock`, `Bangle.load` and some apps
+   * may choose to just call the `remove` function and then load a new app without resetting Bangle.js.
+   * As a result, **if you specify 'remove' you should make sure you test that after calling `Bangle.setUI()`

-   * from the interrupt (when the button isn't held). You will then have to manually
-   * call `E.kickWatchdog()` from your code or the watch will reset after ~5 seconds.
-   * * `hrmPollInterval` set the requested poll interval (in milliseconds) for the
-   *   heart rate monitor. On Bangle.js 2 only 10,20,40,80,160,200 ms are supported,
-   *   and polling rate may not be exact. The algorithm's filtering is tuned for
-   *   20-40ms poll intervals, so higher/lower intervals may effect the reliability
-   *   of the BPM reading. You must call this *before* `Bangle.setHRMPower` - calling
-   *   when the HRM is already on will not affect the poll rate.
-   * * `hrmSportMode` - on the newest Bangle.js 2 builds with with the proprietary
-   *   heart rate algorithm, this is the sport mode passed to the algorithm. See `libs/misc/vc31_binary/algo.h`
-   *   for more info. -1 = auto, 0 = normal (default), 1 = running, 2 = ...
-   * * `hrmGreenAdjust` - (Bangle.js 2, 2v19+) if false (default is true) the green LED intensity won't be adjusted to get the HRM sensor 'exposure' correct. This is reset when the HRM is initialised with `Bangle.setHRMPower`.
-   * * `hrmWearDetect` - (Bangle.js 2, 2v19+) if false (default is true) HRM readings won't be turned off if the watch isn't on your arm (based on HRM proximity sensor). This is reset when the HRM is initialised with `Bangle.setHRMPower`.
-   * * `hrmPushEnv` - (Bangle.js 2, 2v19+) if true (default is false) HRM environment readings will be produced as `Bangle.on(`HRM-env`, ...)` events. This is reset when the HRM is initialised with `Bangle.setHRMPower`.
-   * * `seaLevelPressure` (Bangle.js 2) Normally 1013.25 millibars - this is used for
-   *   calculating altitude with the pressure sensor
-   * * `lcdBufferPtr` (Bangle.js 2 2v21+) Return a pointer to the first pixel of the 3 bit graphics buffer used by Bangle.js for the screen (stride = 178 bytes)

-   * This puts Bangle.js into the specified UI input mode, and calls the callback

-   * Currently supported interface types are:
-   * * 'updown' - UI input with upwards motion `cb(-1)`, downwards motion `cb(1)`,
-   *   and select `cb()`
-   *   * Bangle.js 1 uses BTN1/3 for up/down and BTN2 for select
-   *   * Bangle.js 2 uses touchscreen swipe up/down and tap
-   * * 'leftright' - UI input with left motion `cb(-1)`, right motion `cb(1)`, and
-   *   select `cb()`
-   *   * Bangle.js 1 uses BTN1/3 for left/right and BTN2 for select
-   *   * Bangle.js 2 uses touchscreen swipe left/right and tap/BTN1 for select
-   * * 'clock' - called for clocks. Sets `Bangle.CLOCK=1` and allows a button to
-   *   start the launcher
-   *   * Bangle.js 1 BTN2 starts the launcher
-   *   * Bangle.js 2 BTN1 starts the launcher
-   * * 'clockupdown' - called for clocks. Sets `Bangle.CLOCK=1`, allows a button to
-   *   start the launcher, but also provides up/down functionality
-   *   * Bangle.js 1 BTN2 starts the launcher, BTN1/BTN3 call `cb(-1)` and `cb(1)`
-   *   * Bangle.js 2 BTN1 starts the launcher, touchscreen tap in top/bottom right
-   *     hand side calls `cb(-1)` and `cb(1)`
-   * * `{mode:"custom", ...}` allows you to specify custom handlers for different
-   *   interactions. See below.
-   * * `undefined` removes all user interaction code
-   * While you could use setWatch/etc manually, the benefit here is that you don't
-   * end up with multiple `setWatch` instances, and the actual input method (touch,
-   * or buttons) is implemented dependent on the watch (Bangle.js 1 or 2)
-   * ```
-   * Bangle.setUI("updown", function (dir) {
-   *   // dir is +/- 1 for swipes up/down
-   *   // dir is 0 when button pressed
-   * });
-   * ```
-   * The first argument can also be an object, in which case more options can be
-   * specified with `mode:"custom"`:
-   * ```
-   * Bangle.setUI({
-   *   mode : "custom",
-   *   back : function() {}, // optional - add a 'back' icon in top-left widget area and call this function when it is pressed , also call it when the hardware button is clicked (does not override btn if defined)
-   *   remove : function() {}, // optional - add a handler for when the UI should be removed (eg stop any intervals/timers here)
-   *   redraw : function() {}, // optional - add a handler to redraw the UI. Not needed but it can allow widgets/etc to provide other functionality that requires the screen to be redrawn
-   *   touch : function(n,e) {}, // optional - (mode:custom only) handler for 'touch' events
-   *   swipe : function(dir) {}, // optional - (mode:custom only) handler for 'swipe' events
-   *   drag : function(e) {}, // optional - (mode:custom only) handler for 'drag' events (Bangle.js 2 only)
-   *   btn : function(n) {}, // optional - (mode:custom only) handler for 'button' events (n==1 on Bangle.js 2, n==1/2/3 depending on button for Bangle.js 1)
-   *   clock : 0 // optional - if set the behavior of 'clock' mode is added (does not override btn if defined)
-   * });
-   * ```
-   * If `remove` is specified, `Bangle.showLauncher`, `Bangle.showClock`, `Bangle.load` and some apps
-   * may choose to just call the `remove` function and then load a new app without resetting Bangle.js.
-   * As a result, **if you specify 'remove' you should make sure you test that after calling `Bangle.setUI()`
-   * without arguments your app is completely unloaded**, otherwise you may end up with memory leaks or
-   * other issues when switching apps. Please see the [Bangle.js Fast Load Tutorial](https://www.espruino.com/Bangle.js+Fast+Load) for more details on this.
-   * **Note:** You can override this function in boot code to change the interaction
-   * mode with the watch. For instance you could make all clocks start the launcher
-   * with a swipe by using:
-   * ```
-   * (function() {
-   *   var sui = Bangle.setUI;
-   *   Bangle.setUI = function(mode, cb) {
-   *     var m = ("object"==typeof mode) ? mode.mode : mode;
-   *     if (m!="clock") return sui(mode,cb);
-   *     sui(); // clear
-   *     Bangle.CLOCK=1;
-   *     Bangle.swipeHandler = Bangle.showLauncher;
