When I select "God" in the context menu I get a very, very, very long list of look-up options.

Unfortunately, the title abbreviation column is narrow, non-expandable, and does not show full abbreviation or resource title on mouse over. Somehow, I don't remember that PDCH ... stands for PDCH:O300TCCD which is really Feldmeth, Nathan P. Pocket Dictionary of Church History: Over 300 Terms Clearly and Concisely Defined. The IVP Pocket Reference Series. Downers Grove, IL: IVP Academic, 2008.
I think it reasonable to expect me to know my top prioritized resources. However, I estimate there are 500 entries in my lookup list - I won't guess how many resources. It does, however, exceed my memory or ability to make an educated guess. I need a larger hint as to what the reference is - my preference being full title on mouse over.
