What if you don't want to have to go to a completely different screen to search?
What are you searching for, and what difference does it make what "screen" you're on? Your programs keep running.
I'll tell you what, you download 3rd party software because Windows thinks "convenience" is a four letter word
Well, if you must, go ahead and download a start menu replacement so you can click it, then scroll, then click the app folder you want, then finally click the app you want. You know, for convenience. Or, if you are on the desktop screen, just hit the windows key on your keyboard (to bring up that dreaded start screen) and type the app name and then enter.
Just quit complaining and try it. You will forget about digging through the start menu in no time.
