What would be the coolest thing

[forfear]

if you inserted a line diagram, an organization chart, a business diagram or a company logo as a vector graphic

if you exported it to word, it gets embedded in Word as its native EMF file format. That means no file format conversion required.
if you exported it to PDF, it gets output as a scalable vector graphic, with type faces intact.
if you export it to online outputs like CHM or webhelp, it is scaled/smoothed/sharpened into a compact png file.

i don't know too much about what you are hoping for but i think the coolest things would be:

setting a heading to not be displayed in a toc but show in a mini-toc to actually work
set which columns are displayed in a relationship table proxy
a gui option to pull the 1st heading instead of the title of a topic for toc/xref/breadcrumbs

Well there is an option that lets you choose (or not) to use the TOC heading as the topic title, the touble is it doesn't actually work and it uses the TOC heading regardless of what you set it to. My solution is to do builds using Flare v4.2.
