Ah, here's one little annoyance I have with the current Ristretto: that
scrolling zooms in/out instead of, well, scrolling. When I've zoomed in on
an image (especially with portrait-oriented images) I want to scroll to be
able to see different parts of the image, but then it currently zooms in. I
mostly expect zooming in to happen when I Ctrl+Scroll or Ctrl and the +/-
keys, like in most other applications (like Thunar).

I also think that would be a good default - if the user really expects the
image to zoom when he scrolls and instead it just moves the image up and
down, it's far less annoying than when it would be the other way around,
because panning the image takes far less time than zooming in or out.

Then a thing about keyboard navigation: how can you navigate through images
using the keyboard? Can you just use the arrow keys, do you need to use them
in combination with another key, and if so, can you use the arrow keys when
the thumbnail bar is focused? Also, can there be a scrollbar on the
thumbnail bar this time, so you can see thumbnails of images further away
without needing to click and drag, which is a bit undiscoverable?

Oh, and will Tumbler be used for the thumbnails? ;-)

Anyway, looking good, this is the first time I'm actually looking forward to
an image viewer :)
