Remembering app names is a must. Generally jumping straight to the right letter will let me open the right app with one click, it's only my "S" named apps that have enough apps to require additional any notable scrolling after jumping to the letter (I have 24 apps starting with S, and my screen only shows 15 apps max at once in the Niagara app list).

For all my most used apps, I put them in folders on the Niagara home screen for quick access. I also do this for apps like games where I want to view multiple options at once to decide between them. Anything I'm not accessing often needs some searching to find anyways.
