I hate that OpenTTD makes it hard to clone settings from one game to the next. For new games, it remembers whatever experiment I tried weeks ago and forgot all about, instead of taking settings I like and use all the time. There is a workaround for NewGRFs in the form of presets, but not for the bulk of the settings, of which there are far too many to go through when I want to start a new game. The option to see only basic settings is of no use to me, some settings I use all the time and wouldn't play without are not visible at that level.

I propose a simple fix: When a game is loaded or changes are made in the game, make the new game settings the same. Essentially, the new game settings no longer become a visible feature. They are retained only for the case of creating a new game before any other game is loaded.

Amongst other things, this would allow players to keep presets of new game settings; as many as they like! It's not even "allow players to...", those presets would be retained automatically if the player saved the game. What a convenience!

This is not exactly the same as #5244, but it may be considered to have the same result for less work.
