At first i must say i love this plugin.
What would make it great are: a search option (like a Knowlegdebase), Rating option and maybe groups could be checkboxes instead of search.
Also i noticed a small case sentivity bug. I mad my group like this: Supply (notice the front cap). And when i enter it like this:
[faq order="DESC" orderby="date" group="Supply"] my faq doesn't show.
I must enter it with all small caps: [faq order="DESC" orderby="date" group="supply"].
Please check this for a fix.
