When selecting a pre-configured variable for example, or configuring a variable. It would be kind of epic if we could manage to at least show the user directly the value of what the pre-configured variable currently resolves to.

Eg the ISO Date variable would show directly in the UI when selecting a variable eg "2018-02-19T23:30:15.101Z". Same for Page host, Page path, ... just so people better get an understanding of the value.
