Articles topic (suggestion)
As suggestion,
We can imagine a plugins parameter (i.e: admininfo) working in conjuction with a particular option in the article type parameters - i.e: Type is : "admininfo".
On a wiki page using the plugin article.
With this parameter set to ONLY,
The plugin Articles display only "article type admininfo" alone.
With this parameter set to OFF,
The plugin Aticles display all "article type" BUT admininfo.
With this parameter set to ON,
The plugin Aticles display all "article type" but last admininfo alway stay on top.
With this parameter set to MIXT (or not set),
The plugin Aticles display all articles.
With this, articles are shown on a page keeping a admin (webmaster) important annoncement always on top of it. (great for website general monthly information OR a warning about something).
Neat !
