Actually, separator_left and separator_right don't seem to make the theme.toml that much more complicated.

Do you have a screenshot showing what it looks like when different values are set for them?

[PFiS1737]

Certainly

Example

[sxyazi]

That looks great, this will be a nice improvement!

Could you make this PR only include the changes for separator_left and separator_right?

[PFiS1737]

done

[PFiS1737]

I sincerely request you to reconsider whether the formatting-related features can be merged into the main branch. They are not complex and provide convenience for those who want customization. For others, they can simply remain unchanged.

If possible, I will submit another PR. Those changes don’t seem to be breaking.
