Should we stop limiting ngd publications?

[finnagin]

There have been a few instances where specific pmids that users were looking for to validate results were not showing up that were actually just cut off because of the 30 pmid publication limit on ngd edges. I was thinking that maybe what we should be doing is instead of limiting the list that is returned in the attribute is maybe we could just limit the number of pmids shown in the UI. Any thoughts on this @isbluis ?
