I’ve tried to do this in the program, but it doesn’t work and TAB only works if all the tasks are selected except one. At that time, the program understands the indentation, but if there is more than one task, the TAB button doesn’t work.
Update: The drag and drop to the main task only indents the first task of the multiple ones selected. I really need this feature. Thanks.
Tab works fine in my tests. If you are having issues, please share a sample file and describe a reproducible scenario.
The issue with drag’n’drop seems to be reproducible. Thanks for reporting.
