Hello,
I didn’t find any contact form to contact whonix team.
I wanted just to say that KDE is awfully heavy, uses to much RAM for nothing. I don’t understand this choice.
Other thing I don’t understand how to find a web browser.
Thus I have no time to go further (especially I don’t want to waste time for an OS with KDE), I’m searching something else!
Contact right here

terminal-only and XFCE version might happen at a not too far time in the
future. Stated that in the forums not too long ago.
