Useful program. Could be the center of my daily activities. Would be better-smoother, more integration with Gmail and Google Calendar with, again, better, easy, even default--'scheduled follow-ups' on same screen--Category, Priority, Time/Date. No less important, drag and drop tasks onto other Categorical Tasks to create a Categorical Hierarchy based on Time/Date/Priority-Level in the Task. Then, instantly shows in Google Calendar with a simple, mouse-over 'Zoom-to-Task' in the Calendar.
