feat: a way to tell if the plugin is disabled or broken

[speedlorenzo12]

Feature description

I suggest to color the plugin activator red that has a critical error that prevents it from being activated

Motivation

I am always in the situation where it is not clear whether the plugin is broken or simply deactivated.
