Hope its okay to announce our new free plugin, Server Status.
It is just a basic WP Admin dashboard widget with common statistics and settings in regard to your server and WordPress environment i.e. CPU, load average, RAM (memory) usage, PHP extensions, etc.
Anyway it's not meant to take the place of full-blown
wp-config but at least can show many of the common things that developers like to know while they work
All feedback or suggestions welcome, cheers guys ~
