I think too much (self)micromanagement kill your productivity. A reasonable way to satisfy your need would be planning your day and estimated task duration, doing your day trying to keep the order of task at least and tracking it, and at the end of the day doing a post-day recap for the record.

you end up with a predicted vs reality calendar, and will allow you to eventually adjust your predictions/model based on passed realisations. With no realtime stuff that you actually don't really have the need to deal with in realtime I believe.
