is there a reload hook for figwheel so I can run a partial re-init after it loads?

or rather, I presume there is one; how do I use it?

so I tried :cljsbuild { :app { :figwheel {:on-jsload "gateway.core/reload"}}}, but it doesn't seem to be calling the reload function

also, is there a way to switch the figwheel repl to a different browser connection?
