The
'Create New World'
'Proceed'
buttons inside the Singleplayer and Multiplayer screens are positioned inconveniently at the left side where your mouse cursor wouldn't usually be. It would be much easier to click them and save extra time going over to the left side if they were at the right side instead.
All other 'Done' buttons around the game are conveniently positioned at the right side, but these 2 are an exception at the left side.

To my knowledge, this is how these buttons were always positioned since they've been added. I've thus added 1.19.3 as an affected version.
However, I do agree that this is unintuitive - especially since it is the other way in other screens, so I've confirmed it.
But, these two are not the only place where we have the cancel button on the right. This is also the case in the following screens:
The new "Experiments" screen added in 23w06a
The game rules screen
The "Customize" screen
"Use Preset" in the "Select a Preset" screen
