I have been using this for years and I think it meets your needs. Only problem is that it is paper. I am also a fan of the compact calendar for high level events / sprints / vacation tracking.

I liked that too and was hoping to find a link to a PDF. The URLs on the page are colored so similarly to the text I could barely tell when there were links. Does anyone happen to know if that sheet is available anywhere?

Many of the paper planners you can buy have layouts like this. Are you asking about a digital planner?

I've seen a number of day planners fairly similar, but I haven't seen any quite like that. The grids instead of lines, the combined empty space and to-dos, and the additional spaces outside the days.
