Get a clipboard manager. Being able to access my last 20 copies instead of only 1 is definitely something I wish I set up a decade before I did.

Not only useful for mistakes but also just if you jeed to eg copy someone's bank info to separate fields without doing 4 switches from invoice to bank app

It’s builtin the OS now, via Spotlight.

It's buggy, had to go back to third party application.

Ha? Never had an issue personally. I’m not a heavy user of this feature anyways, so that does not mean much…

Yeah well the thing is that something you can rely 99% of the time is a pain in the ass for a clipboard manager.
