Like many topics lately, this one cannot continue meaningfully until OP addresses Tamas Papp’s points.
Most of plots can be tweaked (see https://github.com/JuliaPlots/PlotThemes.jl for simple examples of how to “theme” your Plots plots), so it shouldn’t be too hard for OP to simply create an “OPtheme” for Plots, and just set that theme. Heck, if OP promises they can actually provide beautiful defaults, I’ll include them in PlotThemes.jl under the name :beautiful.
