I second the thanks for supporting Linux! I'm a proud Ubuntu user, and I used to use WoWMatrix for its Linux support. WM is about useless now thanks to everybody pulling permissions away from them (With good reason I hear from a few authors), so I reluctantly used Curse for a long time. I just heard about Minion, and this site is the first one I used to go to for add-ons so I'm very happy to return and use your client. ...Soon as I find the download section.
EDIT:
So I have it downloaded and installed but it doesn't work. "No modules loaded," won't update to the latest version, and Tools -> Options doesn't do squat.
EDIT 2:
I deleted ~/.minion and reinstalled it and it works now for updating my addons, but it still won't update itself and the Options pane doesn't load at all. :\
As long as it gets my addons updated thoguh I'm pretty happy.
