It makes more sense to me the way ours is, first mode is only top. Most of the time you just want to air out the room with some fresh air, not open completely and have to remove all your plants and lamps or whatever might be in the way.
I second the point about using mostly top mode. There's a small upside to having it the second mode because that way a handle better aligns with force application vector. But yes, makes sense to make it a first mode, too
that way a handle better aligns with force application vector
While that's true, it really doesn't take much strength. It only adds a few cm to the application anyway. So it definitely doesn't tip the scale in its favor, over the convenience of being first mode. 😊
