Count of positions

You have already shown the images. I have already seen the images.

The number of variations has nothing to do with how many moves remain in any variation. The variation can have zero remaining moves (beyond the candidate move being displayed) or it may have 50 moves beyond that candidate move but unless those future moves branch into two or more variations then it is a single variation. Labelling it as a single variation is redundant because just showing a candidate move means it is a variation.

Could you explain the 3.

Sure thing. The meaning of the '3' in your screen shot is that, after the move e4 is played, there are a total of three variations.

There is no way of knowing how many moves are in any of those three variations. There is no way of knowing how far you are from the position(s) that branch into those variations. All you know is that there are three variations.

Here is a video using the older Chess Openings Wizard where I show the number of variations: https://youtu.be/saykgHKUKLA

I get that.

1. When there is no variation left, COW does not display any number, just blank.
2. When there is only 1 variation left, COW does not display any number just blank.

So what I want is for COW to display 1 for one variation and 0 for zero variation, so that the user would know even before the move is made on the board that there is only 1 variation left or 0 variation left.

Let me try to clarify something. There is no such thing as a candidate move with zero variations. Each candidate move is the starting move of a variation.

A position with no variations has no candidate moves. There would be no moves to put a zero next to.

What I tried to imply is that a candidate move with zero variation behind it. See img2 and img3 from my previous post.

When you see 3 beside a candidate move, that means there are 3 variations after or behind this candidate move.
When there is 1 variation behind a candidate move, COW did not display this number 1, it is only blank.
When there is 0 variation behind a candidate move, COW also did not display this number 0, it is only blank.
So what I want is for COW to display these 1 and 0 numbers.

I can say it again but it probably still does make sense to you. There is no such thing as a candidate move with zero variations. Every candidate move IS a variation.

You might be confusing the app with a game database where you'd have a complete game but "with no variations." Chess Openings Wizard does not consider any one line as a game. Every variation is a variation.

For example, if I start with an empty ebook and add the Winawer variation, the Advance variation and the Exchange variation I then have three unique variations.

1.e4 e6 2.d4 d5 3.Nc3 Bb4
1.e4 e6 2.d4 d5 3.e5
1.e4 e6 2.d4 d5 3.exd5

Agreed with that, every candidate move is part of a variation.
But again what I am trying to imply is the number of variation after the candidate move is played on the board (or behind that candidate move). I have already posted some images on this issue. And you also told this in the video.
If the candidate move is the last move then there will no longer be a variation after making that candidate move on the board.

Every variation... ends. That fact that you're near the end of a variation has nothing to do with the fact that you're following a variation. In your example, the variation will end in the position after the last move. I suppose you can say that THAT position has no variations but that's obvious because it has no candidate moves.
