I based a new MARC bibliographic framework on the default one and don´t need most of the fields there, but do not want to delete them, because it´s possible that I´ll want to use them in the future, so I would rather just hide them. But unluckily it´s only possible to hide the subfields one by one and the whole field disappears only after I hid all of the corresponding subfields - which takes very much time to do and is pretty tedious. So what I suggest is to make it possible to hide whole fields in a MARC bibliographic framework with one click (or even to be able to select more of them at once and then hide them all) without having to hide all the subfields one by one first. (By hiding I mean to uncheck all the visibility options by a subfield, or to check the "Flagged" option there.)
Or maybe it would be better to have the option to more generally be able to mass change the visibility of selected subfields (including the option to select them all) on all available levels (OPAC, Intranet, editor). Also to delete them eventually.
