On the beta editor, [https://www.makecode.microbit.org/beta](https://www.makecode.microbit.org/beta), I’m creating custom blocks and am having a bit of trouble.  
On the live lesson, [https://mixer.com/MakeCode?vod=pSTXmomLbkK2SubN1eNlFA](https://mixer.com/MakeCode?vod=pSTXmomLbkK2SubN1eNlFA), it shows that you just press the + button and a custom.ts file is added. However, in the editor it tells me to name my file. I tried naming it custom.ts and no code appeared inside it like in the video. (7:04)

Oh, nevermind.  
I was in a JavaScript-only editor so of course it didn’t work! 😃
