Stepper improvements

[jfisher-bentley]

Feature

Provide some options for the stepper

• Set an icon per step (to replace the step number)
  • To allow showing a checkmark (or other icon) on completed steps
• Allow clicking on 'future' steps to advance directly and skip steps in between
• Thicken green progress line to provide better distinction

Examples

One part of this enhancement request has been released in 3.16.0 🚀 The Stepper step's content can be customised using a stepContent property in each item of the steps array. So, as you suggested, you could now show a checkmark icon for the completed steps.

The others parts of this issue are being considered and are in our backlog.
