Ajenti is a great product. But I agree, it's missing a main feature compared to other control panels: easy GUI domain/site management.
i was about to post the same. I am following ajenti for over a year now and just tried the 1 b version on a vps. It works great, no issues at all but its not user friendly at all to edit configuration files. (to the average user).
I would suggest the same with nginx too, like even editing the main conf not just virtual servers.
They just got 1.0 our the door, give them some time!
I'd like also to be able to edit the virtual host with the same way it is implemented today. Products like Owncloud, Seafile or even Ajenti have sample virtualhosts you just need to copy / paste and a notepad is more convenient in this case.
