Request: Add a "Custom Bar Name" option (change the displayed string for the text on the bar)

[LarssonMartin1998]

I'd love to be able to create custom names for the bars in BigWigs.

When playing a healer I don't really care about if "Dark Voids biggest blast" is coming, I'd rather rename it to names that make sense to me that are saved to my profile, such as:

• Big AOE dmg (raid cd)
• Knockback
• Pull

etc you get the point
