Thank you so much Calum for contributing to the development of Deluge. GTK3 version is available in develop trunk. I am glad that the project is still developing.

You should not only play the Deluge game, but also think about the users who like the program

Do not be offended, Calum, but the development of the project is very slow. Maybe because you're alone in the development team.

For Linux users who are tired of waiting for hi-dpi version
