AlienBlue seems to work pretty well, and is much better (in my opinion) than using Reddit on the browser! It does seem like they need to add support for trackpads or something - the behavior is different when using my trackpad with the magic keyboard on iPad, versus on Mac. I suppose it's because the behaviors, like swiping from the right with two fingers, are mapped to other elements of the Mac OS. I wonder if there could be a way to "give up" those mappings and instead emulate an iPad trackpad?
