Now when I look in to it, it seems that the things I would like to adjust is mostly formatting of imports, and most of these options seems to still be unstable.
Other than a couple already mentioned, I like match_block_trailing_comma. Besides the symmetry, trailing commas in general are good for potentially reducing diffs in the future.
GitHub has a massive majority here with "no repository" being larger than any competitor (a lot of those are probably Github, just not in the toml file).
This makes me sad. I wish alternatives to GitHub were more popular because it just adds that much more friction for a project to move if they have legitimate reasons to want something else.
I think GitHub is fine, but I'm using something else just because GitHub has so much market presence. I wish more people did the same.
