=== Minimal width for workspace buttons
By default, the width a workspace button is determined by the width of the text
showing the workspace name. If the name is too short (say, one letter), then the
workspace button may look too small.
This option specifies the minimum width for workspace buttons. If the name of
a workspace is too short to cover the button, an additional padding is added on
both sides of the button so that the text is centered.
The default value of zero means that no additional padding is added.
The setting also applies to the current binding mode indicator.
Note that the specified pixels refer to logical pixels, which may translate
into more pixels on HiDPI displays.
*Syntax*:
------------------------
workspace_min_width <px> [px]
------------------------
*Example*:
------------------------
bar {
workspace_min_width 40
}
------------------------
=== Strip workspace numbers/name
Specifies whether workspace numbers should be displayed within the workspace
