There are some little things / low hanging fruit that I personally find very annoying, and don’t know why they haven’t addressed yet. Average users coming from Mac or Windows notice these things easily and will immediately write off Linux as being janky when they run into them. Most Linux users I see are fairly apologetic about the rough edges since 1. they know how to figure out how to fix them, and 2. believe in the principles of FOSS.
What do you need the terminal for?
