In Thunderbird, I have "Show Tasks in Calendar" enabled. I can now see tasks on my calendar. To mark a task as completed from the calendar view, I have to go through the following procedure:
- Double click the event
- In the popup, click "Edit"
- In the edit dialog, change status from "Not specified" to "Completed on"
- Click "Save and Close"
This is an insane number of steps to mark a task as complete, a major impediment for anyone trying to be productive rather than fiddling with the interfaces.
- When a task is selected in the calendar view and you open the "Events and Tasks" menu, the "Mark Completed" option is disabled. WHY?
- Why is there no "Mark completed" item in the right-click menu? What about a keyboard shortcut?
- Make the checkbox icon at the left of the task clickable to mark it as complete/incomplete with a single click. Tasks in Google Calendar operate this way (see the three green tasks stacked on May 20 below, the white square is clickable to toggle completion).
