When using a telescope, it is very awkward to switch to first person view to look through it.
It would be great if, when using a telescope, the camera went to it and then returned back

Thanks for the separate report. It will not be possible to simply add a confing option for other mods, since it needs explicit support from them. Even then it might not even be possible, since it needs tight integration with SSR. You might be better off setting crosshair_type to STATIC_WITH_1PP in the shoulder surfing config, rather than adding the desired weapons manually.

It would also be nice if, using the config, you could add items from other mods there, such as weapons, and they would also switch to an enlarged view, and then return back!

If you want to use the dynamic crosshair (moving crosshair) for all items, set crosshair_type to DYNAMIC.

If I have already configured crosshair_type dynamic, then what should I do now? Or do I just need a new line in the document with a command like this to add?> <<STATIC_WITH_1PP_crosshair_items = ["item", and so on>>
If yes, then explain with an example, like last time, otherwise I don't quite understand

Those are just comments for the user (you), so you know what values other than ADAPTIVE and DYNAMIC can be used. You can try out the others if you want. Otherwise you are done.

In shouldersurfing.toml, change

#Crosshair type to use for shoulder surfing.
#Allowed Values: ADAPTIVE, DYNAMIC, STATIC, STATIC_WITH_1PP, DYNAMIC_WITH_1PP
crosshair_type = "ADAPTIVE"

to

#Crosshair type to use for shoulder surfing.
#Allowed Values: ADAPTIVE, DYNAMIC, STATIC, STATIC_WITH_1PP, DYNAMIC_WITH_1PP
crosshair_type = "DYNAMIC"

Done, what next or is that all? You wrote above about the crosshair_type configuration STATIC_WITH_1PP

What about the telescope zoom?

I will be there when it's finished, please stop begging.

Did you succeed?

The vanilla spyglass will work in the shoulder surfing perspective in the next update. But first i want to achieve feature parity with older supported versions of minecraft.
