Thanks for the hard work of @Kee_Kun, we will get the REAL Hotot for Mac. I am sure this one will have native support for OS X, such as Growl notification system and picture preview with Quick Look.
Another good news is that @CSSlayer brings us the QT port of Hotot. It’s more friendly for KDE users and Windows users in deed. With the power of QT, it’s possible to bring about a Windows version of Hotot.
I am sure these two versions will meet you soon.
BTW, please allow me to inform you that Hotot has moved the code repository to github(Hotot@github), for the mascot of github, octocat, is sooooo MOE. I love it, so i did it.
