ToDoList (AbstractSpoon) Support

Hi
I'm a newbie to this app.
It's been great so far and I hadn't known until now there's an app exists which can help me in consolidating my tasks and has in-built planner in one place. ( And so much more )

I had but one silly question though -

How do I do it ? Exactly the title

This option expects there to already be some dependencies set up.

If haven't yet set any up you will need to use the option to create a new dependency.

If you have already set some up then you are being asked to select the black arrowed line that connects two dependent tasks.

Oooohh..
I get it now.
I was trying to "Select the bar" or the "Arrow" which Edit and Add dependencies buttons require.
Turns out I need to tap on those buttons first (and need their respective windows up as shown in screenshot uploaded) Only then will I be able to select either the bar or the arrow.

Thanks a lot, Sir.
