Requiring personal logistics research means this mod can't be accessed in Nullius and (I'm guessing) any other overhaul mod that defines its own logistics technologies. Could you add a mod setting or some other way to make it available without research?

Hmmm.
I think it depends on the overhaul mod if it can be used with LRM...
I'll look into nullius to see if I can handle it.
Perhaps that helps to figure out a more generic approach.
If not I'll go with a setting to enable the mod by default.
Problem might be to prevent interaction with the player if logistic slots aren't available yet. But if I recall correctly, there is a flag somewhere... Hope it is available in overhauls as well...

Have a look at the new version please - I tried to mitigate the problem, but I'm not sure if it will work for every overhaul...
I also added a command and a setting to force-open the gui, but entities still need to have a logistic_point for the mod to work.
