intended unindent behaviour?

Hi everyone,

at the moment I am working on the node edit possibilities.

Moving up/down and indenting works quite well so far. I have also hidden 
the root node in the gantt view. So far I have not checked this in, as 
the milestone stuff that I told you about, is not yet done.

I have one question about the unindent behaviour:

Let us start with

1
     2
     3
     4

When I unindent node 3,

MS Project shows

1
     2
 3
     4

and gnome/MrProject shows

1
     2
     4
3

So MS Project also makes 4 a child of 3 instead of child of 1. And 
MrProject just takes out node 3 and inserts it parallel to 1.

I think the MS approach is more what the user might expect.

 
Which one do we chose? Opinions?

Regards,

Heiko Evermann
