Why am not able to get a grasp of PCB designing?

Another hint: They want the battery terminals as far apart as possible, to avoid shorting them out during assembly or when a wire comes loose. That means two things: follow that advice, or use a battery with built-in protection and drop the protection circuit from your design.

And this gets in to why the selection tools in PCB editors are such a nice thing, drag from left selects only what you fully overlap, drag from right selects everything the area overlaps,

them "m" to move and "r" to rotate, or "f" to flip the entire group in one go, means shuffling around chunks is not as much of an issue. "backspace" removes only the segment under your mouse, "delete" removes that segment and any connected segments back to a pin or a junction,

and finally you can edit traces by starting routing on an existing segment, if you end the trace overlapping a segment on the same trace it can auto-delete the old trace and replace it with your new one (button on the left side turns this on or off)

Putting them on the bottom layer and using ground the ground planes as a shield will definitely help here.

Since this is my first board, I am afraid 4 layers will make it more complex.

I am trying to duplicate what you did, How do you do those beefy traces? Do you draw polygons on the copper layer?
I am not able to pour copper on the board. If i try fill it with GND I get only hatched lines and not solid green layers like yours.

some copper pours, but the BAT trace is a 2mm trace, trace settings are under file/board setup

The pours I have attached my usual settings,

to change how the pour appears, there is a green button on the left hand toolbar, it and the 2 beneath it control what a copper pour looks like, as its easier to lay things out with it hidden sometimes,

edit: you can also change your trace width and grid while routing by right clicking

I tried toggling it but no change.
