Situation:
As an IT-Administrator, we have no time to write technical Wiki-Pages for our collegues. Normally we search for "helping documents" from vendors / manufacturers in the internet and give that (preferred as downloaded pdf) to our collegues.
Problem:
User must open Wiki-Entry, wondering why nothing to see and after some confusion, they find and open the PDF-Attachment.
Solution:
So it would be very helpful to show the PDF content directly in browser, when user opens a Wiki-Entry with no text and just one ore more PDF-Files. Quick and dirty but writing Wikis with nice table of content, they are rare.
