MetacatUI

First - the website looks fantastic. I love the search interface too. A few items (using Mac OS Mavericks, Chrome Version 31.0.1650.63)

Issues
1) some weird alignment issues with the metadata elements/entries on the data package description - screenshot attached (png)

See ticket 6356

2) Data Citation - If the info in the grey box at the top of the description is intended to be a citation you can copy/paste, it needs a few more elements (year, dataset location). If it's not intended to be a citation, consider adding one.

I've added a Metacat ticket to change eml-identifier.xsl to add the year to the citation

Improvements:
1) When permissions are stated as “obtain permission from originator(s)" - helpful to have direct link to contact info
2) First dataset I looked at had very minimal metadata. I didn't realize they chose not to fill out a lot of the metadata till I clicked on the next package. Perhaps “none provided” when missing entire major metadata fields?

This is along the lines of the data attributes being blank, updated Metacat ticket 6355

3) would be awesome to have a dataset preview of sorts - first few lines of spreadsheet, for example.
4) Would be helpful to visually separate metadata sub-headings in on package description page - maybe gray shaded box around text? Made example mockup in jpg attached.
5) Would be helpful to have a description of “data set usage rights”. the entries are very technical and fuzzy, and this might deter the user.
