http://www.landoleet.org/ has it, code is also in the git repository. New in 1.25:
- Optional GIF transparency support -- in some instances this can mean resulting files are significantly smaller. I don't believe this mode makes .gifs that work well with older IE versions, though.
- LICEcap will remember the title between instances (rather than reverting to "Title").
- You can configure LICEcap to auto-stop after X seconds. X=0 produces a single image. (aka Screenshot with optional title).
