- Cursor keys for file navigation:
They are already used for moving the image, and I'd like to keep this
behavior, otherwise keyboard usability would be greatly reduced. When
working on laptops, I am glad about every keyboard control I have.
But maybe use the numeric keypad? The keys aren't needed for input, so one
could use them. OTOH this also break usability on laptops, as using keypad
keys is very cumbersome.
- Broken shortcuts <Alt>-[, <Alt>-]
Yes, that should be changed. This can't work on e.g. German keyboards,
obviously.
If using keypad navigation, * and / would be obvious. + and - are alredy
used for zooming.
Otherwise different shortcuts should be defined. Maybe <Alt>+R for
rotating clockwise, <Alt>+<Shift>+R for counterclockwise.
- zoom behavior
I'll try to implement both zoom options, zoom-to-center will be needed
anyway when the keyboard is used for zooming. This is turning into more
work than I anticipated. ;-)
- mousewheel zoom direction:
I'm also in the forward->zoom into image. My finger moves towards the
image, reducing the distance. This seems a pretty universal standard used
by Acrobat Reader, Microsoft Office, OpenOffice, GIMP, XnView, Internet
Explorer, etc. etc. Only exceptions I can think of are Fraqtive and Opera.
Apart from my personal preference, I don't think it's good to go against
the standard here; intuitive behavior[1] only becomes intuitive by
training, and most people who use computers have been trained for this
specific behavior.
