Hi Joshua,

Thank you for sending a clean explanation by mail, I didn't understand
what you were talking about with thd and paul on IRC.

I agree that in a general way, MARC Editor really need improvement. I
bet the best improvement will be to use another technology than
HTML/Javascript... (Paul's student will work on it I suppose).

At this point, I thought you had found a way to /suggest/ which
tags/subfields were rare and which were uncommon. (Wouldn't it be

Joshua, I implore you to make this simpler on HEAD. If you need 4
boolean values ($display_in_OPAC, $display_in_intranet,
$show_in_editor, $collapse_in_editor), use 4 booleans. Not a 16
values flag. It will be far more readable for the one who did not code
the first version.

The solution you propose is mind satisfaying but hard to
understand and maintain for followers.

Staying on the MARC editor topic, is there a kind of specification for
the future MARC editor Koha needs in 3.0 ? (I mean the one that Paul's
student is supposed to work on)
