Yeah I think what you describe basically leads to the "long list" issue of the blog post. For that reason I really wanted something that uses a calendar layout, but still gives you the reward of checking tasks.

I didn't find anything so made it myself and have been using it for 2 years. As it worked for me I recently worked on making it available to others.. Not sure it is ready for prime time yet (will implement localization for week day names after my vacation), but it works and can be used: https://thisweek.rocks.

(Feel free to drop me some feedback here or https://twitter.com/thisweekrocks).
