Im a CE customer myself and yeah I DID see the plugin. I dont run CPanel though (yet).
About Alberto being all good, I cant say that myself.
Im a web developer myself and I dont see how hard it would be to implement CPanel support automation. I actually did it myself for a custom billing system for a company before. Now, what he's adding in version 1.2 is a little more advanced but damn, last version was released sooo long ago.
Not saying Alberto is bad, but CE is a one-man show and when it comes to releasing new features or fixing bugs it takes a while for a new version to come out.
No problem though, CE is a very nice piece of package & good billing manager
Im not leaving them as a customer also.
