Overriding the default help view

The way I overwrite the default help menu shown in my list app is by setting `SetShowHelp` to `false`,  then rendering my keymap my `model.View()` method as the bottom line.

This works ok but causes me to have to tweak other styling to ensure the components stay aligned etc. I was wondering what would be considered best practice here, and if I'm missing something obvious?
