I'm glad that you like Installatron 5.

Thanks for the recommendation, however there's little to no chance that we'll be adding it to the installers that we maintain. If we add more CMS scripts at some point it will be the well established ones. There are more CMS scripts out there than there are bytes of code in Installatron 5, and they all do pretty much the same thing.

If you're keen, you can try out the new Installer Editor:
http://www.installatron.com/editorStill a little rough around the edges, but if you know how to install Kudos and know a little PHP code, you should be able to get it up and installing quickly. (it's maintaining upgrades in the long run that makes an installer time consuming)
