Retail version of the addon has this option, classic sadly does not.

Describe the solution you'd like
I'd like to be able to have the option to change the opacity of the bar so just the module text shows, in retail version it has it.

Describe alternatives you've considered
N/A

Additional context
Please add if possible, I copied my retail saved variable from WTF to classic and it does work but it spams a lua error that affects fps, I tried copying the code from retail core.lua to classic version but just would break the addon completely lol. thanks, hope you add this.

here is the screenshot of what it looks like, but this is using the retail version of the addon for classic. here the is lua error.

Any update on possibility of this, or does anyone have a simple fix for the lua error? thanks.
