Theme Administration UI
I float this as an idea having found the need to hack template code even to make simple changes very frustrating - which possibly puts off new xoops users altogether. One of the first things you do is pick a Theme for your site (xSwatch4 in my case). These are invariably Responsive 3 panel, 2 header, 2 footer designs because this meets most needs - you only need one or two. A Theme Administration UI, enabling editing of site name, logo, colour scheme etc. would get people up and running very quickly and encourage further use methinks.
