I agree totally.
Honestly, 700ms IS SLOW. No, I am not a Mortal Combat player. But I have been working with computer mice for decades and double-click mouse events are in the range of 250-500ms. 700ms is a really slow double click. MOST PEOPLE double-click in less than 500ms and much closer to 250ms. Again, 700ms IS SLOW. Other people have noted this is slow compared to other brand smart switches as well.
A settable delay would be nice. And if that is too hard to implement for whatever reason, just lowering it to something closer to what the rest of the world uses (250-500ms) doesn’t seem like asking too much and very easy to implement
