I sometimes want to give Message Labels two different colors. But it stays in the first selected color. It would be great if, regardless of how many I select in the Message Labels column, they appeared as small boxes with their colors (like Outlook). The current state might be good, but with multiple options, the list view mode and the reading view mode seem illogical. In short, the same colors as the multiple boxes in the Reading section should also appear in the mailing list. I think that's how it should be logically.
