I played on console edition for 7+ years, and when I switched over to java I couldn’t get used to left-clicking to destroy/attack and right-clicking to place/use items. I swapped over the controls. The only thing that bothers me is how servers always tell me to “right-click” to do stuff but then I realize they actually mean I should left click.

There was one map I saw (undertale) that had a data pack and it was able to actually read my controls and accurately tell me which mouse button to press, I think more things should do that.
