The current way that Variable controls show up on a dashboard are non-configurable. To add to this, they look completely different than the current Dropdown Selector Filter Cards.
My ask would be to allow formatting for the Variable Title and Description to be selected when Editing the Dashboard, with the following types of options:
Text Sizing
Formatting (bold, italics, underline)
Positioning of the text (top, bottom, right, left)
Positioning of the control (centered, right, left, top, bottom)
Following are examples of how Variable Controls look currently when combined with Filter Dropdown Selector Cards, note that it looks wrong, like the designer of the dashboard forgot to set all the text sizing correctly. Note also that the descriptions for the Variable control show up below the object, instead of below the title. Selecting only the Titles, only the Descriptions, or mixing both, you cannot get a consistent look and feel.
