The mod is toggled via a shortcut button.
The research mode is selected via the mod settings, letting you choose between researching all queued techs or for each lab to research the first researchable tech in a queue.

The mod is very vanilla-like, in a sense that everything works the same: you still need to feed science packs to your labs, speed/productivity/consumption modifiers apply, etc. Because the workload is distributed between all available labs researching 5 techs in parallel would take as much time and resources as researching them consecutively (assuming all your labs have access to same science packs).

As usual, if you encounter bugs feel free to raise an issue here or on github, I'll fix them.

Attention!
For some reason science_pack_drain_rate_percent property cannot be read during runtime, so I had to hardcode these values for vanilla labs. If you are playing with a mod that adds custom labs with reduced science pack drain rate then let me know, I'll add their values to the list.
