New Button Slicer - Button and Accent bar size : fixed / auto

[bdarbo78]

As several have already suggested, it would be great to have an option to stop the button size to adjust to the number of values visible in the slicer due to the interaction of other slicers. But there is more.
I mainly use the new button slicer in horizontal mode with the accent bar activated:

My issue is that the size of the buttons and the length of the accent bar is the same for all, regardless of the length of the callout value text. I would love to have an option to :

- automatically adjust the size of each button to the text inside ( this would also adjust the length of the accent bar)

- pad horizontally the buttons left, right or center relative when the number of buttons changes du to interactions
