I’m using GraphicConverter X 4.9 (because that’s the version that came with my Powerbook) and just noticed something cool.
If you open a file, say a BMP (because that’s what MSWindows uses for its screenshots) but want to save it as a PNG (because it’s just much better that way), all you have to do is do “Save As” and name the file with a .PNG at the end, and GraphicConverter is smart enough to change the file type to PNG instead of BMP.
Very cool, very Mac-ish.
(Otherwise I would have had to click on the dropdown and find PNG out of a list of… well, I don’t know exactly how many, but a lot, of options.)
