Difficulties between moving and connection gestures

Moving or connecting cards are two straightforward gestures:

Move: Simple click on a card and immediately start dragging it.
Connect: Simple click on a card and hold until the arrow cursor turns into a open white cursor, then drag away the connection line.

It may be that you need to practice a bit if you find this a bit tricky. The click and hold duration for connecting cards is based on the system setting for the so called "double click" delay, that is the time in finder that recognizes clicking a folder twice top open it. (slow clicking twice on a folder will do nothing, faster clicking will open it)

The "double click" time duration can be set in system preferences: Apple () menu > System Preferences > Universal Access > Mouse & Trackpad > Double Click Speed.
You may increase the time duration until you feel comfortable with it in Big Hairy Goal and Finder double clicking.

Connecting Cards

Q: how can I add a connected item?
A: select a node and click and hold until the cursor changes and then drag away from it. A new node will be inserted as soon as you release.

Q: how can I insert a new item between two existing
A: double click the connection. Or drag from the middle of a connection to an existing item.

Q: how can I delete items or connections?
A: Hover over an item or connection and then press the delete keyboard key. You can also select a range or items and then press the delete key to delete them.

Q: how can I cancel making a connection when I accidentally dragged away from an item?
A: press the Esc key on your keyboard

Q: can I connect two items with a different kind of connection?
A: keep holding the alt key down while making a connection to get a dotted "relation" connection. Additional connection styles can be chosen by right-clicking onto a connection.

Q: When I remove an item that has a parent and child item, do I need to reconnect the original flow?
A: no, once you remove an item, the flow is being reestablished.
