Would it be possible to have the plates in the Dectorio Tab if the Mod is installed?

I've done this already in a mod I made for personal use. Something like this in the data.lua file should work just fine:

if mods ["Dectorio"] then
if data.raw["item-group"]["dectorio"] then
data.raw["item-subgroup"]["display-plates"].group = "dectorio"
end
end

Good idea. Since this is an enhancement, I will bundle it with the upcoming GUI overhaul I have planned and will not release a separate version for it. Be patient :)
Also, I think it is reasonable to activate it only by a non-default configuration checkbox, since some may want to keep it in the default tab even with Dectorio enabled.

Text plates does this already so I got thinking why not this too.

Added in 0.18.2.
