Is there a plugin that exists that will block every item from being researched without having to put the shortnames of each item you want blocked?

https://umod.org/plugins/blueprint-manager can do it, but you'll need to put them in manually.

https://umod.org/plugins/research-block can do it too, but again; you'll need to put them in manually.

Yeah I checked out both of those plugins but didn't see the option to just block researching all together. Thank you for the list though!

Try setting the 'busy' flag on ResearchTables when they spawn.
