TL;DR
An entity where I can set name and icons for blueprint, if created blueprint contains this entity, name and icons are set from the entity

What?
I want a special item, placable on surface, where I can set some settings for blueprint, at least name and icons, ideally parametrization details ...

It would be interesting to know, why don't process each planet in a separate thread/CPU core?

Factorio, probably, the only one game, which works perfect on MacOS with multi-monitor configuration.
(it allows to choose default monitor, cursor doesn't left monitor, Dock doesn't disappear, etc)

special thanks to: annoying notification about game mode doesn't appear in debug mode

The "Close window" shortcut (Cmd+W) will be disabled starting from 1.1.82. Cmd+Q (Quit Factorio) and Cmd+Opt+W (Close all windows) will continue to work.
It's a greate news about Cmd+W. It would be also awesome to have autosave before quite. Sometimes I close Factorio via Cmd+Q by accident.
Anyway ...
