To be clear, we do think collaboration is important and have spent multiple years working on it: working first on sharing/delegating individual tasks with individual people, then concluding that this goal was too limiting—that we needed to extend our vision to support sharing of entire projects with an entire team (and optionally syncing those projects with OmniPlan).
We’ve done a bunch of groundwork on sharing projects with teams and syncing them with OmniPlan, but through that effort we concluded that the OmniFocus 3 design wasn’t very well-suited to a sharing workflow. Its design simply wasn’t flexible enough to accommodate the additional information you need to know when sharing tasks with others, particularly in our mobile iPhone and iPad apps. To that end, we embarked on a complete redesign and reimplementation of the apps with flexibility in mind, keeping collaboration in mind as an explicit long-term design requirement. Redesigning and rebuilding OmniFocus has been a multi-year effort, but the resulting OmniFocus 4 is now in TestFlight on iPhone, iPad, and Mac, and we look forward to shipping it as soon as possible so we can resume our work on shared projects.
