Colamanga & Bookwalker

[MusicArchon]

Hello, it's been some time since i've been using HDoujin Downloader (but first time on the forum ^^) and I want to say first : Thank you for your work !

Do you think it might be possible to add Colamanga to the list of the supported sites ?

And while i think it may be more difficult, what about Bookwalker ?

Thank you again !
