Daily Godot Tip #39: You can create code regions between #region and #endregion that allow you to collapse that entire section into 1 line
(programming.dev)
Useful for things you don't edit but still would need to scroll past
I think having region boundaries part of the code makes sense. Is the alternative having file and line number references somewhere else? They could fall out of sync all too easily.
But the open/collapsed state of the regions? That should be per-user IDE state, the last thing we want us that becoming diff noise in the repo.
