The menu bar is hidden in the installer because that's how the Lisa's installer looked. I definitely need to do some work on layouts to make things more responsive. If your phone's screen is too small the text may overflow and things can get cut-off. But I don't want to cram scroll-able panes into all these dialogs because the Lisa didn't even do that.

I'm balancing historical accuracy with modern constraints with my own self-imposed technical debts, so there's bound to be compromises!
