Created attachment 3477 [details] [review] Proposed Patch
Not sure what this means, but there are multiple search buttons on the advanced search page on purpose - it was an added feature a few releases ago to make it easier if people just want to use one part of the advanced search and not scroll all the way down.
On reading the patch I see that it is removing the feature - I don't think this patch should be signed off on - but if it's a problem for some libraries it needs a preference to control.
The duplicate button is a feature, not a bug. If libraries need to be able to hide it I suggest we make sure the markup allows it to be hidden with CSS.
Yes, I added the extra search button at the top in Bug 3663 at the request of several of my sites. If there are a lot of item types in the system, a user might have to scroll down a long ways to find the original search button, and we got a lot of complaints about it. I would hope that this feature stays.
i'm strongly against a syspref. But i'm OK for a css property. And I agree we can discard this patch. The problem is that library X want "white" and library Y want "black". Plus library Z prefers green... Sometimes, we must say "hey, it's OpenSource, but we should concentrate on important things..."
