While the Theme Engine was an integral part of the CyanogenMod 7 experience, it has been strangely absent from CM9 nightlies. Fortunately, they’ve reintroduced it, all spruced up for Ice Cream Sandwich. Now switching themes is as easy as opening an app and pressing one button. Themes are also in the convenient form of installable APKs. The whole system is convenient and easy to use.
If that wasn’t enough good news, they have also added customizable lockscreen shortcuts. While this is catching up with AOKP (which has had that feature for ages), this comes with a handy UI instead of AOKP’s unintuitive menus.
While CyanogenMod used to be known for its extensive customization features, it seems that AOKP has taken that crown. More and more people are using AOKP over CM9 lately. However, the Theme Engine should draw in a good crowd, as this is a big advantage over AOKP.
