Great work, finally something like irfanview for the Mac!
It is tiny and makes a fast workflow possible! Thanx for the effort!

Did you consider the suggestion of post 690? The fixed
proportional selection would be nice to crop for those online
services that print out photos on 3:4 sized paper. Also having a
predefined square proportional selection would be helpful sometimes.

Irfanview for example shows the selection information
in the title bar: current cursor position, width, height and ratio

cheers,
