Thank you! This is close to what I am looking for. I'll give it a shot and see if it addresses my problem.
update1: Hmm. So it doesn't exactly address the core problem, which is I can still easily access those other apps that I wish to uninstall. So in a way, this app helps by making the UI less enticing to click on, but it doesn't address the core problem, which is to fully uninstall.
