Thanks for your reasonable reply and question! As for what I love about UI, it's simple;
I don't have to remember what to enter, just the pathway to get there.
With command line, you have to remember commands, arguments, syntax, and gods forbid you enter something wrong. It won't work.
But with a (decently designed) UI, you merely have to remember the path you took to get to wherever you want to go, what buttons to press, what mouse movements to execute.
As someone with a limited attention span and energy to do things, this is a lifesaver.
As for Visual Studio, that's a development preference. Code is too different for me to be comfortable in it, and relies on command line too much.
