Trigger Editor: autosuggest possible matching mappings for the selected interface

[davidebriani]

It's currently possible to create triggers on data coming from an interface. To do so, the user navigates to the Trigger Editor, select an interface, and manually inputs the preferred interface mapping of that interface.

However, this is currently tedious because the user has to remember which mappings exist for the interface, and type them correctly.

It would be a good UX improvement if the editor suggested the existing interface mappings to the user, once the interface has been selected. Ideally, the autosuggest should work also for parametric mappings.
