In Acrobat 9 Pro, there was a Portfolio layout called Grid with File Preview. We use it as our primary layout for PDF portfolios because it allows users to rapidly view PDFs within a portfolio. This was our primary reason for using Portfolios. Unfortunately, this important feature was removed in Acrobat X Pro resulting in clunky and very slow PDF viewing.
Adobe needs to immediately reinstate Grid with File Preview into Acrobat X Pro. Until this happens, I will continue to use Acrobat 9 Pro.
I encourage everyone to use the Feature Request/Bug Report Form to submit this as a Bug. Unless everyone complains, nothing will happen.
