Just installed 4.0, and though I haven't tried it yet, I just want to give compliment to a minor detail during the installation process:
You actually gave me A CHOICE wether I wanted icons on the start menu or not. I always get annoyed when I can't choose, so thanks for that minor detail!
Same goes for the "send to" option during installation, a quite useful function.
4.0 is just missing one thing, something I've been missing since I started using this excellent program: PNG support. Heh, guess I'm the only person here who saves my work in this open source format. =)
Nope, you're not the only one. It has been requested before, and I too prefer the PNG format in many circumstances...although I tend to use TIFF7 to save my digital photos.
