I think a great feature would be to include some sort of support report inside of admin tools where users could easily gather server and extension information when reporting issues to forums.
Simply provide output on common needed things as a text you can copy or a txt file.
Things such as
Joomla version
PHP version
MySQL version
Components installed and their versions
Using .htaccess?
Versions of ioncube or zend for those who may need it
Or any other common things you see
This would cut down on time required on both ends with just a simple report. However, I think some of it would need to be selectable (turn on and off in the report) so you do not compromise too many versions for security reasons.
Just a thought when I was making a support post elsewhere. Who knows, just a suggestion :-)
