Wordpress plugin "One post widget"
This is my second WP plugin published. I was looking for wordpress plugin which could display automatically last posts inside different widget areas preserving their queue. There is strong possibility that already exists but I could not find one. So I had to build one myself. You can download it from here.
I created it May 2012 and have maintained it since.
Desctiption
You can display last post in widget area so the widget's title/content is given post title/contents. No listings- only selected post itself fills widget area. You can choose queue which one to show from recent posts. Currently it supports showing content from recent posts or just by post/page ID. Please see screenshots from wordpress plugin site- they should be self explenatory.
Hopefully it helps someone out.
