Learner Onboarding - more customisability

We have been playing with the new Learner Onboarding feature, but find the form builder to lack some basic features that we'd really love to see.

Of particular note:

Formatting of text in the Description of each field - e.g. bold, underline
Ability to add URLs or pop-ups/overlays - e.g. linking to a privacy policy or disability supplement that provides more lengthy info in a pop-up box or external page
Ability to add non-field content - e.g. a text box with additional instructional information, or an image showing an example ID
Simplification of Address entry - e.g. 'Is Postal Address the same as Residential?' shortcut, Australia Post address suggestions.
More control over the question presentation itself - e.g. field currently labelled 'Indigenous Status' but we might prefer to word as 'Are you of Aboriginal or Torres Strait Islander origin?' (without having to create a new section and use the description to elaborate instead)
