That's a bit of a cheat, but I think a good idea.
But that's not the job of this mod.

May be the mod should add a hint "already read"?

Thanks! The change I'm going to make is to make the first page read almost instantaneously. I think we all use this mod because it makes it easier to mark which books we already have, and I'd like to be able to do that more quickly.

@Oh God Spiders No
Of course.

Do you mind if I copy and modify this for a new mod?

Thank you so much for making this. So much more convenient than preparing a shopping list.

@star
This is not a steal but a transfer.
I want you to receive it without minding.

Well, if you don't want to do it, stop this talk.

Well, I don't like steal credits. That's why I prefer improve existing mods. Nevermind then.

@star
I think that good, but you should make mod. Not me.
I am thankful, but I cannot take responsibility for your code.

I meant such code:

It's more compatible with everything and it's shorter a bit. Use it please.

absolutely brilliant idea !! At least to me.. i need that, very thanks

@star
This is a makeshift mod for me.

I thought so, but I quit because it seemed to take time.
If you can make it better, please make it.
Then this mod will be withdrawn.

Everyone has to think of another way of distinguishing between books they own and books they don't own.
Or ask to the indie stone.

Why do you replace whole function? It make the mod incompatible with future updates of the game and with other mods. It's better to use neat injection.
