Is it possible to increase Max Job Queue ? I couldn't find any config file or anything

Except hardcoded value here: https://github.com/phantamanta44/Lazy-AE2/blob/1.12.2/src/main/java/io/github/phantamanta44/threng/tile/TileBigAssemblerCore.java

Would be great if it would be possible.

not at the moment. i'll work on adding a config option

Awesome! Would be really good :) Or another idea: You could add a block that would increase Max job queue.. For example 4 per 1 block and real maximum would be set in config. This would be really good i think.

I really love your mod and something like that would be great i think.
