Yea, we thought about that but decided it would be cool to have the apps in Quus to be public so that it can be shared with friends. For example, I sent my Quu link to my mom earlier today.
Makes sense. I don't personally mind this, but it's not something that I expected (to me, "personal app store" implies privacy). It's probably worth making this more clear on your landing page.
Kind of wish you suggested more than just 4 apps, it'd be fun to browse a bunch and really take this for a spin.
