Superscripts in Plots.jl with units

Doing:

julia> using Plots, Unitful

julia> plot([1,2,3]u"s", [1,2,3]u"m/s")

produces this y-label:

image

Shouldn´t it produce m s^{-1} with a proper superscript?

In parallel, is there a way to show units in a prettier way in tables in Pluto. For instance:

It would be nice to have proper \mathrm{mol~kg^{-1}} units shown, and even better if the units were placed on the column titles, i. e. \mathrm{m_3 / mol~kg^{-1}}.

Note: Latexify.jl does a pretty job there, but unfortunately it has to be inserted all over the place in the notebook (as far as I know), and that is not convenient.
