Better Slicer Formatting for Ranges (timeline view), Horizontal view, and Dropdown menus

The timeline view for slicers was a recent addition when using date fields with the out of the box slicer visualization. However, your ability to format it is quite limited. This view should be available to fields other than dates (like a max/min price range for example). In timeline view, it has a location to enter a start and end date manually. I would like the ability to turn these on or off. I would also like the ability to control their display location similar to legend values, or set the start box at the beginning of the range line and end value at the end of it. Currently I am forced to leave both in the top left corner. I would also like the ability to label them so I know what values they are representing. With the Horizontal slicer view, I would like the ability to format the colors for all conditions (selected, unselected, hover, etc.). Currently, the formatting is forced to black for selected items and we do not have the ability to alter the color of selected items background or text. With Dropdown menus, we do not have the ability to alter the formatting of the visual when it is showing the full dropdown range. I would like to be able to change the text and background colors from black text on white background.
