Unfortunately this is still not enough, since after closing the rar it won't remember the last image viewed. Forcing us to navigate again the directory structure and finding the right image. Besides, the image rendering engine is not quite good, even for black and white images.
On my V2, I can browse .zip files, but I can't open files inside the zipped archive (I get an error). Not tried RAR.
Regarding the image rendering engine - indeed. I made a brief article detailing how you can make the images look better - Optimising documents for a 6" eink display
In brief, I've noticed you obtain far better results processing the documents in advance on your computer. (i.e. downscale & reduce colours using your PC prior to putting on the device).
