Make property values fields in step templates as links
I wanted to edit properties of step template. The value of property was read only and it wasn't obvious how can I change it.
Finally I noticed that label of property is clickable. The property name doesn't have visual indication(e.g. underline) that it's a link/button.

The better UX will be to make value field as link to open the same Edit Property dialog.
Alternatively you can make the value field as an editable textbox to change value inline.
