A: Great questions! Any tasks that get left behind on a previous day stay there. But you get an alert in your day that there are items left behind. You can then reschedule them or check them off, unschedule them etc. So if you want everything not completed yesterday to roll over to today it takes only a few clicks.

We will likely introduce an option for automatic rollover, but there are advantages to doing this deliberately.

Keep in mind that when you sync a calendar you can sync items as tasks, events or time blocks. So those items behave differently. Events and time blocks stay on the day. They won't get put in the reschedule dialog. Only tasks do. So you want to think about what the items in your calendar represent and sync them accordingly.

You are right that Marvin is similar to focuster. Focuster is basically a subset of Marvin's features. Just like in focuster you can drag items into a day, or into an agenda, sync your calendar, estimate task length, see a progress bar for today, go into focus mode etc. etc. The one thing Marvin does not have yet that focuster has is auto-scheduling. You have to make a manual plan in Marvin. This is on our roadmap however.

Marvin is a bit less expensive than focuster (premium plan) and has many additional features. So you are not looked into the day planning workflow. But you can also create smart lists and work from those, or make a weekly list or do batching etc.
