[Koha] Removing a field from a biblio in Koha 3

[José Miguel Parrella Romero]

Greetings,

In the cataloguing interface, when a field is repeatable you get a '+' 
sign next to the field, which you can happily click and repeat the 
field. This also reflects on the marc blob. But now I can't find a way 
to delete the field in the editor -- even if it has no data, it keeps 
showing up.

What I did now was to fiddle with the marc blob for the biblionumber and 
delete the MARC references to the repeated, data-less field, but I don't 
think this is the right way. Is there anything in development regarding 
this issue?

Thanks for your time,
Jose
