[Form] Is it possible to have a specific name for the form?

You can create input with type "hidden"

ohhhhhhhhhh okay I'll do that. Thank you @Bogdan !

Is there also a way to set the preset E-Mail-title and that header block showing in incoming E-Mails sent from a form?

Maybe this is what you are referring to https://github.com/webstudio-is/webstudio/issues/4414
