Agree with Samuel R. I would like customisable templates, e.g. meeting template such as that provided by Samsung S-Note.

This is one of the most awaited feature for me :-)

Similar suggestions have been made at posts below, but I think this is the most general one. Being able to import a pdf as a page type would enable everybody to produce whatever page type he likes using whatever tool he likes and use it in Papyrus.
Personally I would produce various plane tessellations using postscript (and then converting to pdf).

There are several related propositions. How about we collect all votes for this one:

I use the "pdf-import" to write on my own background (f.e. with gray squares).
It would be great, if I could past a new page oft this pdf-import.
(or I could make my own background in papyrus)

I would love to see some options for templates as well.

This is a great idea. Right now I have created a PDF and then import it, but it would be much cleaner if I didn't need to do that every time.

I work for a Structural Engineering firm, and we use a standard, pre-printed "notepad" for doing hand calculations. I'd really love it if I could set up a template in Papyrus and do all my calculations directly from Papyrus

Custom forms uploaded to the aplication to allow overlay. If i am meeting with a client and going through a discovery meeting, i would like to be able to standardize my notes so i have similar forms between clients.

The available features allow for self designed forms already, it would be great to have the option to save these as templates.

I would like to make my own template that I can use over and over for new pages.

There are other programs that do this well enough. I feel it slows things down to have to click through options when note taking should be fast and simple.

+ interactive templates like "Trip memorial", "Meeting checklist"
+ allow creating own from PDFs/JPEGs

An absolute must, I do meeting notes with Papyrus and really wish you could have template headers for meeting participants, title etc.
