can i change the size of my thumbnails in the thumbnail browse list? my textures are a bit complex sometimes and the small thumbnails can not show me enough details to make me decide which texture i want to choose .
 is there a way i can increase the size of the thumbnails when i want to replace a texture for an object ?
i looked around everywhere but i can not find an option to do this .
in mac osx i can increase a thumbnail view , that comes very handy most of the time. i would like to be able to do this in Blender. 
i don't mean to zoom in on the screen , that will result in a pixelated view. 
but a real increase of the thumbnail size while browsing in the thumbnail list.
No, there no option to do this currently.



However there is a patch in the tracker to support this: https://developer.blender.org/T27830(It's not expected you should make your own patched Blender builds, just noting that it may well be supported soon)
