We've decided to include SuperFlexi in the core. We're doing this because it provides a very simple way for developers to create things like page banner sliders, icon blocks, image galleries and a whole lot of other things. We're in the middle of developing several new skins for the mojoSkins project and each of these skins will require SuperFlexi. We really think it would be best for all users of mojoPortal if SuperFlexi is a core feature.
The next release of mojoPortal is coming soon. In the next couple of weeks.
