❓ FAQ:

Q: My colors are bad
- You can change the colors with the hi option.
- If you have no background color, you should try to set blend.mixing_color to a color that will blend with the background color.
Q: All diagnostics are still displayed
- You need to set vim.diagnostic.config({ virtual_text = false }) to remove all the others diagnostics.
Q: Diagnostics are not readable on a light background
- You can either set vim.g.background = "light" to use white diagnostics background. Will not work if hi.mixing_color is set
Q: GitBlame (or other) is displayed first
- You need to modify the virt_texts.priority option to a higher value.
