        .SYNOPSIS
            The event handlers shared by every app entry on the Install tab

        .DESCRIPTION
            A scriptblock literal inside a loop is a new scriptblock every time round, and
            building six of them per app is the single largest cost of drawing the app list:
            measured at 2.13 ms per entry against 0.62 ms when they are made once and reused.

            None of them close over anything per entry. They read the sender through $this, so
            one instance serves every app.
