I am looking for a pdf reader which refreshes when the pdf is updated, while staying (roughly) at the same page it was before the refresh.
Adobe and Foxit don't refresh. Preview does refresh, but gets you back to the first page after every refresh.
The reason for all this: I am using Texstudio to edit LaTex files. TexStudio has an internal pdf viewer which does exactly what I want (refreshing when I recompile the pdf, and staying roughly at the same position in the pdf). But Texstudio only allows you to open a single pdf viewer window. I would want to open several to be able to look at the pdf output in different places at the same time (it would significantly improve my productivity).
