问题
I wass looking for quite some time now how I could see the file type icon of each file I have opened in visual studio 2012 tab well, like it was shown on previous versions of visual studio. This was completely removed from vs 12, couldn't find any option enabling this. This is something extemely usefull when having many open files.

I found that this option exists on the registry! So you go here:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\DialogPage\Microsoft.CustomDocWell.Options
and change the IconInTabs property from false to True!
File type icons are displayed again next to each tab!!!!
Edit: In order for this to work you must have installed Productivity Power Tools 2012 plugin
