Thought I'd create a distinct thread from the previous one asking about daily use, because I really do want to hear more on people's pain points. Great to know people are generally sounding pretty positive in those posts who recently switched, but want to know your difficulties as well! This way old and new users can share their thoughts, hopefully to inspire a respectful discussion.
I looked at docker because it seems to be able to do anything I think I might want it for, but was told to reverse course and learn the system first before going deep into such complicated systems.
