I using your server from years. It's very good and easy to use.
I would like to suggest to integrate NGINX server as front and to keep Apache on the back. It's running fast. It's very easy to integrate. At digitalocean.com I found a help how to do it. I will be happy to see it as part of Uniform server.
Also will be nice to be pre-installed ioncube loader and DBG (PHP DEBUGGER - dbg-php-5.4.so /.dll).
