I used it for a few weeks. It was fun for a while, but then I realized I just stopped using my Trello board, and they were always competing for screen space. Also, there was no way to view it on mobile.
I am now using a new system on Google Calendar. https://www.youtube.com/watch?v=wf6D0aUAEdI
In addition, I color code by importance: Red (Due soon, important), Yellow (important but not due soon), Green (someday).
Also, I realized I could add emoji's to calendar events https://www.youtube.com/watch?v=iLa57pekyZw.
