 --- Raw Notes ---
 
-- It should be forgiving when you forgot to stop a task. Maybe a specific
-  command, instead of "stop" use "forgot" or directly "edit".  Then I would
-  like to express either "stopped 30min ago" or "it lasted only 1hour”.
-
-- Use display granularity/resolution to see more or less details.  This would
-  combine nicely with a tag hierarchy. (Tomas Babej)
-
-- Need reports to help users doing fixed-rate work - finding the longest task
-  for example.
-
-- If an interval has more than one tag with a defined color, and is being
-  rendered, then use the first tag color. It doesn't really matter which.
