d0ne - Smart Task Scheduler

This update makes d0ne faster, smarter, and much better at working with your real calendar setup. You can now connect more than one Google account, and d0ne will schedule tasks across your connected accounts so your availability is respected everywhere. Calendar settings have also been moved into a dedicated Calendars sheet, making it easier to see connected accounts, manage active calendars, and sync your timezone from Google Calendar. New tasks can now be added from Shortcuts and Siri. Create a shortcut with the d0ne Add Task action, say the task out loud, and d0ne will add it and schedule it in the background. We also improved the way tasks sync with Google Calendar when you mark them done. Completed tasks now update their calendar blocks more reliably across connected accounts, including when several tasks are completed quickly. The task list should feel more stable and responsive too. Optimistic updates for creating, completing, and deleting tasks have been tightened so cards no longer bounce back during quick actions, and the new-task glow now follows the correct task even when tasks are added in quick succession. Finally, this release includes performance and polish improvements across the glass UI, scheduling rules, calendar handling, and task animations.
