I tried to find the original comment on HN, it was very informative, but some chess master (grandmaster?) commented on here that until you are highly rated (say 2200), the only thing you should focus on to improve at chess is to improve your ability to notice tactics in games. He went into more detail but I can't find the post :(

Not quite. First you need to eliminate your own hung piece blunders and look for opponents'. But that gets you to 1000-1500 then you need to notice tactics.

There is overlap, in that the simplest single-move tactics (forks and skewers) are almost the same as catching immediately hung pieces.

I would argue that hung pieces are just single ply tactics. Also significantly you must notice your opponents tactics as well as you own.
