When accessing the NPC page during a session I need to know a few things very quickly, and almost never what is actually shown on that page.  I'd like to know things like their accent (if any), the short personality blurb, and maybe where they are (for ease of finding the right one).  Being able to pick and choose which fields are visible from the NPC summary page would help me get the info I need immediately without having to tell my players "hold on, I'm trying to find something...".     In addition, it's extremely frustrating to input all this information about NPCs and then NOT be able to access it easily.  Having the NPC name hyperlinked to their details page would be a trivial improvement that would make my job as a DM one thousand times better.  A link to the display page would be perfect, and then I can click the Edit button as and if things change during the PCs encounter with him/her/them.   Finally, being able to filter the NPC list would be enormously helpful since the number of NPCs in a campaign only ever grows, and sometimes exponentially.  Being able to see only those NPCs that have a certain location, or any of the other fields that are visible on the summary page would make accessing related NPCs much, MUCH easier.
