Hi all,
I have got an idea for a new plugin, but i do not have the time to implement it.
There is the line which symbolizes the end of line (Settings->Editor->Gutter and Margins).
I think that a line which shows the end of the page could make sense too.
You could setup the page (A4, A3, etc.) and than a line could be shown.
If you write a Function and the page changes two lines after the function head, you could add two more newlines to let the function start at the next page.
I hope somebody likes this idea too and has some time left.
Paddy
