Print in another window for better performance - you could export/print and write at the same time.

Good idea, maybe we can use a headless Electron window for export/print.

Nice features and some UI suggestion:

1. Put Info tab content bellow Export Options, and no need to give it an individual tab. Because it has no settings of export PDF/HTML.
   

2. Narrow the vertical scroll bar, maybe 5px is ok? or just hide it?

I prefer to have a separate start page and not the options on the first page. @Jocs What do you think about that?

I'll narrow the bar a bit.

What do you mean a separate start page?

A separate tab like the Info tab in the image above - keep it as it is.

We can borrow the UI from Chrome print setting modal in the future, and show a preview page on the left.

That's a good idea and also brings better export/print performance because it's doesn't block the editor. BTW page number are currently not supported because it's not possible with pure CSS or current Electron.

Yes, you mean a separate window, it will bring better performance.

@fxha I found that I can not set the margin/padding in the export setting now, and header/footer also can not be setted?

Could you please explain the issue or provide a gif? Any exceptions or so?

It works well now, I export it in the morning, the Page and Header & Footer seems disappeared, but I can not reproduce it again.
