New features for Tree Widget

Question

I have been using the Tree Widget lately & was wondering if the following features can be added to this

1) Colors

A mechanism to specify colors to the text in the tree.

2) Space out nodes

A mechanism to space out nodes without actually creating an empty branch. For example, if I do the following

@startsalt
{
{T
 + World
 ++ America
 ++
 ++ Europe
 ++
 ++ Africa
}
}
@endsalt

Then there would be 5 branches created under World, of which 2 will be empty.

Answer 1

For colors use <color:#colorCode>

@startsalt
{
{T
 + World
 ++ <color:green> America
 ++
 ++ <color:#b80>Europe
 ++
 ++ Africa
}
}
@endsalt
