Pre-print menu and better layout of PDF export

✨ What new feature or change would you like to see added in RemNote?

Slightly cleaned-up PDF export, and a pre-print menu.

1. please can you remove the massive white space on the right of the document (please see attached PDF)

2. before actually printing or exporting the pdf, can there be a print menu where we can select the below for the PDF export

   1. if we want to remove the file path (i.e. parent rems) at the top of the screen. Or maybe this could be moved to the very bottom of the screen as a footer?

   2. if we want to buttons that are basically useless when the rem is exported as a PDF, such as the pin-to-sidebar button (the star), the flashcards button, the share button, the AI editor button

   3. if we want to print the PDF with all rems expanded, or if we want the expanded rems to just be the ones that are currently expanded on our page

      (we currently have to remember to expand all rems before printing/exporting and I always forget to do this. Also, maybe we want to export the PDF with all rems expanded, but on the actual RemNote application we only want the currently-expanded-rems to remain expanded)

   4. possibly adding page numbers to the PDF

🤔 What problem does it solve for you? How would it improve your workflow or experience with RemNote?

Sometimes I like to print important documents and keep them in physical folders I have for a subject. Or I would print a document I want to keep that document visible to me at all times (e.g. I would use split screen but I don’t have enough space on my screen so having a full print-out of the document/rem would be useful). Or if I’ve got a class (I’m in high school) where my teacher doesn’t want us to have our laptops open, I can print off the relevant rems in advance of the class.
