Allow custom scripts to run in a plugin?

Maybe. I haven’t looked too much into it until just now be honest.

I just looked at another thread (Script Runner: Run scripts without running the game) and OP said the plugin got removed.

Look at this, too:

Nevermind what I said before lol because you definitely can’t upload plugins that use loadtring() or otherwise execute scripts for any reason, BUT it seems like you can use it personally as a local plugin. if you’re unsure probably CTRL+F the Terms Of Service for plugin stuff.
