TypeScript compilation progress indication Follow

I'm working on a project where TypeScript compilation takes several seconds to complete. I'm using the "Track Changes" option in WebStorm, but I find it hard to know when compilation is done (and thus it's time to reload in the browser). The only indication I could find is that the TypeScript output window is updated, which doesn't help when if are no errors or the errors remain unchanged. Am I missing some feature that gives feedback on compilation status?

Thanks!
