beamer
I'm using the beamer class with note pages. In the upper right corner I see always the slide the notes are referring to. Is it possible to change the size of this preview?
\documentclass{beamer}
\setbeameroption{show notes}
\begin{document}
\section{foo}
\begin{frame}{foo}
Some text.
\end{frame}
\note{Many notes}
\end{document}
Here's a sneaky way to accomplish this without using any external tools. It's a "proof of concept" more than a complete solution, but I think it would be usable if a little rough around the edges.
It uses an enhanced pgfpages. The enhancement means that when pgfpages comes to lay out its logical pages on a physical page, it can do so on more than one physical page. So what we do is we gather together the notes page and the next frame page then typeset them as usual: notes followed by frame (since the frame is the next one), but with a little extra: we also put the frame page in the top corner of the notes page.
Modulo a little trickery to ensure that we start and end at the right points, and that we actually don't want to use the full frame but only its contents (ie not the background), this isn't overly complicated. It does mean we get two extra slides: one at the start and one at the end, but even that could be dealt with without too much extra hassle.
The enhanced pgfpages is called pgfmorepages.sty (CTAN and github). With that, the following code works-for-me:

Of course, one ought to hide that horrible stuff in another .sty file. Also, I've no doubt that there are better layouts - I just hacked the current one that puts the image of the previous slide in the top corner.
This produces the following.
Edit 2014-09-20
In response to anderfo's comment (which I never got round to looking at) and a similar question by email, I proffer the following. First, I should say that as it has been a long time since I looked at this code, I find I no longer fully understand it! However, by my usual 'hack and see' approach, I've managed to get something that (I think!) simulates the "show notes on second screen=left" layout. It also corrects the offset that Jim points out (again by "magic numbers", not by understanding what's going on).
(One minor annoyance is that on the last slide, a "next slide" still appears. I've not figured out how to get rid of that.)

A note page isn't implemented as a normal beamer frame, but typeset using its own code which can be found in beamerbasenotes.sty (cf. \beamer@outsideframenote, ll. 59-103). Therefore, using normal frame options like shrink or allowframebreaks isn't possible.
Best Answer
Beamer's template
note page(inbeamerouterthemedefault.sty) defines how are note pages constructed. The slide size in note pages is hard coded in this template. By default, notes title uses.25\paperheightand slide in it and slide in notes is reduced to.25\paperheight x .25\paperwidth.In next code I've copied
note pagetemplate and changed notes title and slide in notes proportions to use.45\paperheight. It's not an elegant solution and it reduces available space for notes. May be someone else will provide a better answer.
