OmniFocus 4.9

OmniFocus 4.9 adds support for Siri AI, optional new date parsing assistance via Apple Intelligence, and a range of new and updated App Intents exposed as Shortcuts actions.

[…]

In our testing we’ve found that the new Siri AI hasn’t yet learned how to work with app capabilities that it hasn’t specifically been trained on, even for App Intents that are available in Shortcuts and Spotlight. For example, its understanding of how to work with OmniFocus is based on how it’s been trained to work with the Reminders app. Our work in OmniFocus 4.9 means that Siri now knows about “reminders” in OmniFocus (i.e. actions and Inbox items), “lists” (i.e. projects) which contain reminders, and any “groups” (i.e. folders) that lists have been organized into. Siri can assign and edit reminder due dates, flags, repeat schedules, and notes and image attachments in OmniFocus. This is another great leap forward! But as soon as you try to go beyond what Reminders can do, you find its limits: for example, it doesn’t understand the distinction between due dates, planned dates, and defer dates.

Siri also doesn’t really understand much about how our document-based apps work, because Apple hasn’t trained it on our specific apps or anything equivalent. So, Siri doesn’t know how to make an outline, or a diagram, or a Gantt chart. We expect this to improve over time—after all, we’ve worked with other language models that do understand how to make those things—but it’s important to understand Siri’s current limits.

With Siri AI, Spotlight becomes even more important as a source for personal context. You can ask Siri about content in your OmniFocus database, so Siri can summarize the actions you’ve completed this week, or tell you what items you might consider working on soon.

My favorite change in OmniFocus 4.9 seems less exiting, but I’m irrationally happy about it. Last year, as part of the Liquid Glass update, they redesigned the Perspectives Bar on iOS to automatically collapse and expand as you scroll. I found the animations distracting, it messed up my muscle memory, and it required lots of extra taps. In 4.9, there’s a new Show Perspective Bar option, which you can set to Automatically (the 4.8 behavior), Manually (stay collapsed but expand when you tap), or Always (show the expanded state all the time, nothing moves). This is, of course, what I chose.

I’m still seeing the previously mentioned glitches in the Mac app with tabbing, spontaneous tag collapsing, and the window moving itself between spaces. The iOS app sometimes still shows an out-of-date list of flagged actions.
