Theres a network toggle within each app settings to allow/disallow access so a dedicated app isn’t necessary, its really easy to add aurora store and the other third party apps you like, and idk what the panic button does but I’ll look it up. As for it being bare bones, thats kinda on purpose since its all about you being in control of what you want on the phone without compromising security, just customize it how you want. I say give it try, I did and don’t regret it.

Edit: searched what the panic button does and it seems interesting but it does only remove some data but not all of it so it seems kinda pointless to me imo. However people are asking for an improved version so depends on the development team and priorites
