> that "minify script" is a bad idea
that applies only when you are using custom plugins and not the default C2 plugins. Because most of the custom plugins are not supporting the minify script, also its better not to use it, unless you export for html5 only. Nw.js and Android/IOS compilers might get really buggy that is from my experience, but maybe im doing it wrong.
OP-that groups are useless - and cpu intensive
