In your video you complained about small GUI elements that demand too much precision from the user and recommended a "runway" approach, reasoning that "the less precise you need to be the faster you our". Okay, fair enough. But here in the forums you complain about increased travel distances being inefficient, which your very own "runway" concept would actually produce. The very mouse gestures you love being the perfect example of that.
But for the sake of argument let's assume for a moment that greater travel distances are less efficient. Well with the alt-tab method I mentioned you instantly see all open app names at once with very helpful preview images, which is an objectively faster way to identify them than your method of moving the cursor all the way down to the bottom of the screen and across each icon to see the name of each, one at a time. And there displayed in the center of the screen closer to where the cursor most likely already is. And finally you only have to move your cursor to the exact app you want once identified. Meaning the alt-tab method is faster either way because it requires less travel distance and precision overall.
However, I get the impression that none this really matters because the crux of the issue for you is just having to upgrade to Windows 10. But that's just something your going to have to accept and move on with your life.. or not. So I'm just trying to help you in that regard. There is not perfect solution or GUI "enlightenment" (whatever that means) coming to save you. At least not any time soon.
. I would like to apologize though for probably coming off a bit too derisive in most of my comments thus far. This is due to the fact that honestly your complaints are becoming less and less coherent and outright contradictory the more I read them, which makes trying to help frustrating.
