How to adjust font size of the control labels in Manipulate?

Questions
1

Hi,
Manipulate does a lot of work by automatically labeling the various controls based on the list of parameters I supply. I noticed I can give my own labels if needed. However, in many cases I notice that the default font used for these labels is smaller than what I would like it to be. Is there a way to increase the font size of these labels - either auto generated or explicitly given?

Any Manipulate variable can be specified with a three argument list:

{x, xInitial, xLabel}

So, for example, you can do this:

Manipulate[x, {{x, 0, Style["Label", 24]}, 0, 1}]

Or another example, where the label rotation is tied to the Manipulate variable:

Manipulate[x, {{x, 0, Dynamic[Rotate[Style["Label", 24], x]]}, 0, 2*Pi}]
