Advice sought on breadboard, schematic and pcb?

Beginners’ advice sought on breadboard, schematic, and pcb ?

Breadboard - How do I show leadouts from the breadboard correctly so they show on the schematic and pcb

Schematic -

Why does the schematic show a number of components way off, and not connected to anything? and then also not on pcb.

Do I assume white/black dotted lines are the width of the track ?
Any ideas what the green, blue, and purple dotted lines mean?
What does the different solder holes coloured green and red mean?

Many thanks

This is because you have to rearrange the parts and route the wires yourself

@gray_b please upload the .fzz file

The colored dotted lines are virtual wires. They indicated that the connection was made in the schematic view or the breadboard view, but not yet in your current view (the PCB in this case) The color is random, to make them easier to track visually.

You still need to route them for a complete PCB. You can adjust them with the mouse to turn them into real traces.

Green dots mark connectors that seem ok. Red dots mark connectors that are not yet connected properly, like, only with a virtual wire.
