Really enjoying using this program, good work!

I have a question on the way the program handles the project end date.  If I have 3 tasks a,b and c.

If they all have 10 days duration and are setup up so when 'a' finishes, 'b' can start and then when 

 'b' finishes 'c' starts.  This means that the project will have a duration of 30 days.  If 'b' is then finished 

 and set to being 100% complete before 'a' has finished, the project end date is not brought in.  It just

 leaves a space.  Can this not be done automatically?

The problem I have is that the resource is occasionally doing tasks that are planned for later.  When they 

 do the task that has been completed, it does not show any update in the project end date.  I have attached an image of this.  

I guess you could say that if they are able to do a task that happens later and is dependant on a predecessor that it 

 is not truely dependant.  I did this to keep a linear project.  Maybe it should have been dependant on the 

 resource availability.

Your help is truely appreciated
