A think I really would like to see in Softaculous is the small "GetSimple" CMS system, it's very lightweight, and is not even database driven, it runs via XML files, and is pretty fast, and open source!
I've tried to create a package myself for the script to my server, but I did fail
Personally I think that CMS is so awesome, and many people should really try to use it, to see how easy it is, for smaller sites, like a portfolio, or a small simple site, I've used it myself to some websites, and I really recommend it, for same reason I would like to see it in Softaculous!
