It is great when in the list of candidates for presentation other data
may be stored similarly like it is stored in tabuluated-list-mode
where one can get the ID and full entry of data, and similarly how it
is stored in Helm where I can select the presented string such as:

"Joe Doe" and get the ID 2

and that is where sometimes duplicates could appear and it is fine for
duplicates to appear in those cases, as user may know that second Joe
Doe is from Mexico, first one from USA, so choosing second below would
reach to right ID which ID is then hidden in the presentation.
