I mean - you can use J and K to rotate screen for 10° (which I don't find too useful) - as it is written in the pull request, the major rotation used are 90°, 180° and 270°. In fact it would be great to use Shift+J to rotate screen for 90° in one direction and Shift+K in the other one. And somehow to fix centering of rotated pdfs...
Another thing - on my k3w when you want to get to the next page in a PDF you have to use the rigth buttons > and <, not the left ones < and >, because the left ones do not work.
Thanks for your reply.
