I would like the option to customize the colour used for focus areas when you're tabbing through an app made with Instant Apps or Web AppBuilder. This option is present in Experience Builder as an accent colour in the colour scheme you can customize. This makes it possible for users to create apps using their branding colours, while still make the focus areas visible to end users. Right now, the colour in Web AppBuilder is a mid teal, and in Instant Apps a bright blue, and both colours easily get lost in other colours you can use to design the app.
