During workshops and presentations over the past few months, one of the most frequent requests I've heard is for a way to create and edit models without requiring PHP coding (or having to install any new models as plugins). I've given this some thought, and we now have an official feature request: MDL-61806
Please take a look and comment, either in the tracker or here. What would you need in a model editor? In particular, how would you expect to be able to define targets and indicators?
Please don't comment in this tracker or in this thread about reporting or display enhancements-- I know we need those as well, but we should address those separately.
