I like the idea of combining a todo list and a calendar.<p>Here&#x27;s a UI concept:<p>Every day, it shows me the standard 9-5 &quot;time grid&quot; of 30-minute blocks. Maybe it would show them a week into the future too, like the &#x27;week&#x27; view of a calendar app.<p>Underneath, I&#x27;d have my stack of TODO items. Every morning, I would drag a few items into the blank spaces on the calendar to plan my day. Then, I could check things off as I finish them. If I fall behind, no bigs: just drag the old items onto tomorrow&#x27;s time grid sometime.<p>I&#x27;ve tried to simulate this with Trello. That&#x27;s a great way to get the &#x27;TODO&#x27; part down, but it isn&#x27;t so great for planning my time.<p>I&#x27;ve tried this with Org-mode. This really comes the closest out of all of them.
