[Koha-devel] Staff/OPAC ISBD views and subfield visibility

[Katrin Fischer]

Hi Andreas,

I might be misunderstanding your question, but the OPAC visibility 
setting should take effect on all pages and views in the OPAC now. It 
didn't use to, which was considered a long standing bug and finally 
fixed. Now it's possible to hide fields from OPAC that can still appear 
in staff in a reliable way. The preconfigured visibility settings in the 
frameworks might not always be ideal - if that's what you mean, we could 
work on improving them.

Hope that helps,

Katrin
