Do these things allow me to define functions and to call them on focus change, on windowshade, on iconification, on other events? Can I evaluate text returned by a command spawned in those as part of my config, at any moment? Can these functions differentiate between windows by mask? By state? BTW, can I have custom states? Can I have conditionals there? Schedule those functions? Change that schedule?

Yes.

I wouldn’t. These are different things for a different workflow.

And nobody cares about your workflow, sorry. Go convince one of 3 other people.

Where there? Yes. consulting the official documentation. It not that fuckin hard dude.

I know you are not an adult.

You’re the one who immediately started name calling dumbass.
