@Ryohz: As of today, there are still some technical difficulties implementing the pinch-to-zoom feature properly. If only Apple had documented the (strange) behavior of the raw data readout from Magic Trackpad 2... then we would already have had this feature one year ago. It's difficult to explain there, but basically it's the readout reliability problem with 2 fingers specifically. And there is no point to publish the buggy feature.
Battery info - no such capability. In fact, nobody had ever requested it before.
Just in case, here is the current features summary (can be useful for newcomers). Basically, an ExtraMagic software adds the 3/4-finger gestures to the standard 1/2-finger mousing features (those of Apple-provided Magic Trackpad 2 driver from the Boot Camp 6.x package), as following:
* 3-finger dragging, 3-finger tap, 3-finger horizontal and vertical swipes
* 4-finger tap, 4-finger horizontal and vertical swipes
All of the above is configurable by user (a dozen of custom actions can be assigned from the drop-down menu for each gesture in ExtraMagic settings app). But the default setup already makes the gestures work in Windows 10 quite similarly to OS X.
And, just in case, here is the default setup of the ExtraMagic with Magic Trackpad 2 on Windows 10:
4-finger tap: middle mouse button (for example, opens web tabs in background, activates auto-scroll, or can do other things depending on the application you work with);
4-finger horizontal swipe: back/forward navigation;
4-finger vertical swipe: Task View / Show desktop navigation;
3-finger drag: dragging (by the way, according to email feedback from people it's often preferred over all other 3-finger gestures);
3-finger horizontal swipe: not active by default, but available if 3-finger drag is disabled;
3-finger vertical swipe: not active by default, but available if 3-finger drag is disabled;
3-finger tap: not active by default, but available if 3-finger drag is disabled.
