What do people think of Make OS X Great Again?
Hiding updates notifications is pretty bad from security standpoint.
The only way I can answer the question "Which problem does this app solve" in a meaningful way, is in relation to its author, that is: "It helps paying my rent".
Being a power user and knowing these things are just settings that people are not usually aware of (or maybe not easily available and require some terminal-fu), 10 USD feels a little expensive for things that you can easily do for free. Maybe add options enough to justify the price tag but, for what it offers today, 10 is a little too much.
Been using the app as a beta tester, you soon forget about it but then realize you are less annoyed by the small little things like iTunes or the update notifications. Also i hide very often my desktop icon to make some quick nice screenshot
