As an old fart, what annoys me is that people constantly draw schematics with LTspice that do not follow the conventions of normally drawn ones.
Inputs on the right side, top, or bottom, bits of circuitry hanging out like barnacles.
OK, that's really the fault of the user, but other things like showing ac sources as DC generators with "ac" written on them are just plain dumb!
Little "noobs" keep coming up with silly circuits which won't work in the real world, (things like Op Amps with resonant LC networks in their feedback loop), & LTspice will either work, or will not give any clue as to what the user has done wrong, so they come on here, expecting us to sort it out for them.
I thought, "Maybe I'm a nasty old turd, & I'm unfair to LTspice", so I decided to download it & just try some simple circuits.
It was just as clunky as I had suspected--- took ages to work out how to draw the simplest schematic, & don't get me started on running tests!
If they went out of their way to put obstacles in the way, they couldn't have done better.!
If I can build the real thing & test it in less time, I'd say that is a fail for a simulator.
And as I've said before----"Get off my lawn!"( I'm thinking of making that my signature!)
