Suggestion: Custom indentation of child tree nodes in the Task Tree
Suggestion: allow for custom (wider) indentation of child tree nodes. The goal would be to have all child subtasks appear further to the right in relation to their parent task, in order to improve readability. If Windows tree view control does not allow for horizontal extension of dotted tree structure lines (the lines that link child items to their parent item), just pad child tree node labels on their left.
In a perfect implementation, a tree view would become a "tree list view", with tree view nodes on the left (expanding downward) and resizable list view column headers on top (expanding rightward). A user could then visualize (read) the first "column" of a tree view as a distinct list of level-1 tasks, the second "column" of a tree view as a distinct list of level-2 subtasks and so on.
