Synctex support
Summary
This is a feature wish to bring back Synctex support to Papers
Description
First of all, thanks for the initiative! I think this is a much needed refresh.
I looked through the NEWS and discovered that you dropped Synctex support. I understand the technical reason of maintainability, but regarding the practical usage of the feature I can assure you that there are many scientists like me who much prefer editors like Vim/Emacs over a full IDE or some integrated single-purpose TeX editor to write their documents, and so this feature becomes quite useful.
Unlike the DVI feature for example, Synctex is very much alive and widely used today. Please consider bringing it back!
