Hi,
There's a new release of Calatrava now available. This is another bug fix release. More details here:
In brief, this fixes bugs around generating stylesheet directories, supporting *.scss as well as *.sass and using timers on iOS.
In other good news, there are at least two new projects now using Calatrava which is going to see more and more rapid improvements (hopefully.)
For upcoming features, I am starting to think about how to manage tablets.
