Version: 4.3.4 (using 4.3.4 (KDE 4.3.4), Debian packages) Compiler: cc OS: Linux (i686) release 2.6.32-trunk-686 I think, if you add second check-box, near check-box - "Flat View" for view only "Sub-to-do" without parent to-do it be more useful. For better example: you click this check-box and if "to-do_one" have sub-to-do, then "to_do_one" hide and sub-to-do view in "Flat View" mod, if "to-do_second" don't have sub-to-do, they do nothing. It opinion have same my friends and it is not all users. I think, this option you can add in configure. P.S. sorry, I have not good English, because my default lang is Russian (-:
Better done with a filter.
