I wish there were a few more options for organizing completed items or moving items around. For example, I accidentally left an item running on Thursday last week and incorrectly cancelled it today when I meant for it to be complete. I can't now record it as complete for Dec 7.
Pros: Clean DesignPomodoro Style Scheduling Works
