Is there a way to clear the error indicators that show up in the editor?

if you press escape near an inline display, that makes it go away for me

That clears the result, but not the little diamond animation.

does Proto REPL: Interrupt work to kill the diamond spinner?

Yes, thanks.

The self-hosted REPL is for ClojureScript, right? Does it work with CLJC files?

maybe someone else can answer, the self-hosted repl has basically never worked for me

Everything I do just gives this error: "TypeError: Cannot set property 'user' of undefined"
