Enable custom and conditional formatting for all slicer elements

Please enable fully customizable and conditional formatting for slicers, including:

• Customizing the format of the check box for shape and colour, selected or unselected
• Enable hiding the checkbox and allow slicer option selection to work on just the displayed text item, so that a slicer item can function as a tile or button selection
• Enable conditional formatting so that slicer options can be displayed differently when selected/unselected
• Enable use of conditional formulas for slicer conditional formatting
• Enable a fixed text literal option and/or optional text based on a conditional formula for slicer tooltips so that "help" text can be surfaced for a slicer.

It seems patently ridiculous that - important as the slicer tool is - the full range of formatting options available to the basic Table visual does not carry over to the slicer visual.
