DevPlanner supports standard clipboard operations, such as Copy, Cut and Paste.
Select task or category and click menu Edit->Copy or Edit->Cut to place it to clipboard. To paste it to another category inside current or another plan document click menu Edit->Paste.
Plan entries will not be copied after copying a task or category. To reorganize existent tasks structure use drag-and-drop instead.
