[Feature] Formatting options for custom tags

[rubcap]

Is your feature request related to a problem? Please describe. Automatically assigning different colors to different custom tags is very convenient 👍. But these colors may or may not make the custom tags stand out compared to the Trello labels (e.g. dark-blue custom tag vs. blue Trello label). Also, each user has a different taste, and users may want to have more control over the custom tag formatting.

Describe the solution you'd like Some ideas:

• Ability to change the font for custom tags
• Ability to change the font size for custom tags
• Ability to choose a different color palette for custom tags (e.g. grayscale/rainbow/dark/...)
• Ability to choose between custom tags with a colored outline

Describe alternatives you've considered This may be related to the fact that custom tags are desaturated (see my earlier feature request)), but I have been disabling custom tags because I couldn't live with the colors (and enabling them afterwards because they make the [tags] stand out better).

Additional context I understand that setting the formatting for each custom tag separately is superfluous (too much work), but more formatting options for all custom tags would be welcome.
