I don't think I do, no. I'm really a fairly novice user, since I've only used Ubuntu here and there since 12.04 (I think) and not committing until 18.04, then switching to Debian Jesse with... I think it's GNOME. So basically the same thing as Ubuntu? I do wish I understood more about the underlying tech and window managers and such, because I know I could get more out of it all, but I really just follow poorly written blog tutorials for settings things up until it's "good enough". I am scared to play around much more for fear of everything becoming unusable, since that's been my experience in the past with the ALSA/Jack/PulseAudio mess and with video card drivers.
