Task dependencies / dependencie views

editing dates for existing tasks
The date-picker shows up fine but when a new date is being picked it does not show up properly in the task list. (I just tried it out one more time and it seems that one has to hit the enter-key for the changes to take effect.)

predecessors
The input field does not have a border or background color. That makes it hard to find for the first time. Also after populating it one has to hit the enter-key for the changes to take effect.

Why does does the time span for a task have to be at least one day? A task might take 30 minutes or a couple of hours.
If task A starts on the 8th Feb. and ends on the 9th Feb. and task B starts on the 9th Feb. as well it can not have the task A as predecessor.

Why not have the ability not to use dates but durations only? For instance it would make sense to say that task A takes 11 hours and task B takes 16 hours. It should be possible to simply specify that task B starts once task A has ended.

Also it would be nice to be able to specify that for instance task B automatically starts when task A starts.
