It is a great software. Much better than paid options out there. I tested it on Mac and Ubuntu. I wanted Windows version too but was reluctant to install it. Is there a portable version of it? I like to keep it on pendrive.

Edit: Don't mind, I loved it so much and I could stop myself from installing it on my Windows machine too. But I still want the portable version so that I can use it when I don't have admin privileges to install software.
