Estimated and real time
You can enter the estimated and real times to each card. This helps you to estimate the total amount of time for the whole project even before you began to work on it. On the other hand this allows you to compare the estimated time with the really needed time.
DeadlinesYou can enter a deadline in each card. Unresolved tasks which deadline is overdue are getting highlighted in red so you can pay them specially attention.
Different time units
You can set an inidvidual time unit to each column. So you can plan the time in the column "Ideas" in hours while you plan the time of the column "In progress" in minutes.
